    2x -6x+q is not an equation, it is a polynomial.

    Given that the equation 2x 2-6x+q=0 can be formulated into the form of (x-p) 2=7, then x2-6x+q=2 can be formulated as (x-p) 2=( ).

    Solution: 2x 2-6x+q=0, x 2-3x+q 2=0, (x-3 2) 2=-q 2+9 4, so p=3 2, -q 2+9 4=7, so q=-19 2.

    x 2-6x+q=2,(x-3) 2=11-q=41 2, which cannot be converted to the form of (x-p) 2=( ). can be transformed into (x-2p) 2=41 2.

    Analysis: Equation x -6x+q 0 can be reduced to:

    x-3)²-9+q=0

    i.e. (x-3) 9 q

    From the original equation of the title can be formulated into the form (x-p) = 7.

    Then p=3 and 9 q 7 i.e. q=2

    So x -6x+q=2 can be reduced to: x -6x=0 to obtain: (x-3) -9=0

    i.e. (x-3) 9

    So x -6x+q=2 can be formulated as (x-p) = (9) Hehe, children's shoes, next time pay attention to don't pay attention to ** problem! This is a waste of your time and an unnecessary drain on the energy of others!

    The equation x2-6x+q=0 can be formulated in the form of (x-p)2=7, which is easy to know p=3 and q=2

    So x2-6x+q=2 is x2-6x+2=2, which can be formulated into (x-3) 2=9

    (x-p)^2=7

    x^2-2px+p^2-7=0

    i.e.: -6=-2p, p 2-7=q

    Available: p=3, q=2

    So x 2-6x+q=2 can be combined into (x-3) 2=9

    Solution: (x-p) 2=7

    x^2-2px+p^2-7=0

    i.e.: -6=-2p, p 2-7=q

    Available: p=3, q=2

    So x 2-6x+q=2 can be combined into (x-3) 2=9

    I've given you some advice, like this question should be written in its entirety (there are no answer options), but you ignored it.

    I have seen that other people have answered you with wrong questions, or the process is not standardized, and I have given you very standardized answers, and you do not [accept the answers].

    Therefore, I have not answered many of your questions, but there are indeed good ways to answer this question, so let's answer it and see your attitude.

    Solution 1: x -6x + q = 0 i.e. (x-3) = 9-q This equation is again (x-p) = 7

    9-q=7x-6x+q=2, i.e., (x-3) =2+(9-q)=2+7=9, so the form is (x-3) =9.

    Solution 2: x -6x + q = 0 i.e. (x-3) = 9-q This equation is again (x-p) = 7

    q = 3x -6x + q = 2 i.e. x -6x + 2 = 2

    That is, x -6x + 9 = 9

    Therefore the form sought is (x-3) = 9.

    1.Simplification (x-p) 2 = 7

    Get x22px

    p2=7, i.e. x2

    2pxp2-7

    0, and then according to the corresponding equal coefficients can be obtained:

    The squares of the front coefficients are all 1, which must be equal; The coefficients to the power of x to the power of 1 are -2p and -6, respectively, i.e., -6

    2p, i.e. p3; Finally, there are the coefficients of both sides of x to the power of 0, which are p2-7 and q, i.e., p2

    7=q, and because of the above, we get p

    3, i.e. 3*3-7=q

    q=2;Draw conclusions

    3, q=2;

    3.Substituting p3, q=2 into x2-6x+q=2 gives x2-6x+2

    2, ie. x2-6x

    0;It should be possible to match x* (x-6);

    Analysis: It is known that the equation x2-6x+q=0 can be formulated into the form of (x-p)2=7, and an equation about q can be obtained by formulating x2-6x+q=0, and the value of q can be obtained, and then the form of x2-6x+q=2 formula can be determined by using the matching method

    Solution: x2-6x+q=0

    x2-6x=-q

    x2-6x+9=-q+9

    x-3)2=9-q

    According to the title, p=3,9-q=7

    p=3,q=2

    x2-6x+q=2 is x2-6x+2=2

    x2-6x=0

    x2-6x+9=9

    x-3)2=9

    i.e. (x-p)2=9

    Knowing that the equation x 2-6x+q=0 can be matched to (x-p) 2=7, p can be found according to the above equation

    x-p)^2=7

    i.e. x 22pxp 2

    2px=6x

    p=3x^2

    2pxp^2-7=

    x^2-6x+qq=

    p^2-7=2

    So x 2-6x+q=2

    x^2-6x

    x^2-6x=0

    x^2-6x+9=9

    x_3)^2=9

  11. Anonymous users2024-01-28

    Solution: Because: (x-p) 2=7

    So: x 2-2px + p 2-7 = 0

    Because x2-6x+q=0 can be combined with (x-p) 2=7, so: 2p=6 is p=3

    p 2-7=q, i.e. 3 2-7=q

    q=2So: x 2-6x+q=2, i.e.: x 2-6x=0x 2-6x+9-9=0

    x-3)^2=9

    That is, x 2-6x+q=2 can be combined into the form of (x-3) 2=9.

    From x 2-6x+q=0, it can be formulated into the form of (x-p) 2=7, then x 2-6x+q is equivalent to (x-p) 2-7;So (x-p) 2-7=x 2-6x+q is brought into x 2-6x+q=2 to get (x-p) 2-7=2

    So it can be matched.

    x-p) 2=9.
