Anonymous users2024-02-10Solution: From known conditions, obtained.
3b-2=0
2a-b-3=0
The solution yields a=11 6 b=2 3
Original = 10a-5b-12a+4b-4+4a-3b-1 22a-4b-9 2
Substituting a=11 6 b=2 3 into an algebraic formula.
There are 2*11 6-4*2 3-9 2

Anonymous users2024-02-02Because the absolute value is not negative.
So 3b-2=0 2a-b-3=0
b=2/3 2a-2/3-3=0
a=11/6
Substitute the values of a and b into 5(2a-b)-2(6a-2b+2)+(4a-3b-1 2).

Anonymous users2024-02-01.1. Obtain the system of equations according to the meaning of the question:
3b-2=0
2a-b-3=0
The solution is: a=11 6, b=2 3,5(2a-b)-2(6a-2b+4)+(4a-3b-2)=10a-5b-12a+4b-8+4a-3b-2=2a-4b-2
11/3+8/3-2=13/3，2、（-2ab+2a+3b）-（3ab+2b-2a）-（a+4b+ab）
2ab+2a+3b-3ab-2b+2a-a-4b-ab=-6ab+3(a-b)

Anonymous users2024-01-311.Since both terms are greater than or equal to zero, the formula 3b=2 2a-b=3 is reduced to 15-(8a-b+10)=5-(6a+2a-b)=5-11-3=-9
2.The formula is simplified to -6ab+3(a-b)=-6+12=6

Anonymous users2024-01-30Solution: 3(2a-3b) 0 2|5b-2c|0 is not a negative number.
and is 0, then.
3（2a-3b)²=0 2|5b-2c|=02a-3b=0 5b-2c=0
2a=3b 5b=2c
10a=15b 15b=6c
That is, 10a = 15b = 6c
a:b:c=3∶2∶5
Since the root number 3 is the proportional middle term of 3 a and 3 b, (3) = 3 a*3 b, so 3 (a+b) = 3 >>>More
Remember: |a-3|is a positive number, (b+4) is also a positive number, and the addition of two positive numbers gives 0, which only means that both numbers are 0, so |a-3|=0,a=3,,(b+4) =0,b=-4, so a+b=-1
Solution:1. Because a+b=3, ab=1, 1 a+1 b=(a+b) ab
2。Because 1 a+1 b=5 >>>More
1) f(x)=ax 3+bx 2-2x+c, then f'(x)=3ax^2+2bx-2
and f'The two roots of (x)=0 are x=-2 and x=1 >>>More
a=3 belongs to a, which means that 3 is the element in a
There are two possibilities. >>>More
