Anonymous users2024-02-11The theorem of the length of the sides of a triangle is that the sum of the two sides is greater than the third side.
2m>x
x+m>m
Got:0Is this an equilateral triangle??
The root of the quarter is numbered three a
This is very common, and it can be remembered as a formula

Anonymous users2024-02-101) Since the sum of any two sides of a triangle is greater than the third side.
That is, m+m>x>0
That is: 02) Seek high first, using the hook theorem.
h=root[a 2-(a 2) 2]=(root3) 2*as=1 2*a*h=1 2*a*(root3) 2*a=(root3) 4*a2

Anonymous users2024-02-091.You pass the equation by the sum of the two sides greater than the third side and the difference between the two sides is less than the third side.
2.What is a bottom triangle I only know an equilateral triangle If it's an equilateral triangle, then it's three lines in one, and you can make a high line and you can make two right triangles, and the length is a a 2 3 2a and then you will always be there.

Anonymous users2024-02-05(1) Because m (m is not equal to 0) is the root of the unary bipolar equation x 2 + nx + m = 0 about x, it is obtained by substituting it into the equation.
m^2+mn+m=0
m(m+n)=-m
m+n=-1
2)(x-1)(x+2)(x-3)=0
x-1 = 0 or x+2 = 0 or x-3 = 0
x = -2 or x = 3 in x = 1

Substituting the equation.
m^2+mn+m=0,m(m+n)+m=0,m(m+n+1)=0
m+n=-1
Or, find any number where m is not equal to 0 and bring it in, and find n
For example: m=2 then n=-3, which is suitable for fill-in-the-blank questions.
2）x1=1，x2=-2，x3=3

Anonymous users2024-02-03(1) Substituting m m into the equation, getting m 2 + mn + m = 0 and then removing m to get m (m + n + 1) = 0
Because m is not equal to 0, m+n+1=0
i.e. m+n=-1
To make the equation 0, simply make any of the brackets 0
i.e. x=1 or x=-2 or x=3
2003(x-y)+2004(y-z)+2005(z-x)=y-2x+z=0 x=(y+z)/2
and 2005 (z-x) = -2003 (x-y) -2004 (y-z) into 2003 2 (x-y) + 2004 2 (y-z) + 2005 2 (z-x) = 2004 >>>More
