7x2 -4x -5x2 +2x = 2x2 -2x
How do you solve for the problem x squared minus 10 equals 4x plus 11?
x2-10 = 4x+11 x2-4x-10-11 = 0 x2-4x-21 = 0 (x+3)(x-7) = 0 x = -3 and x = 7
What is 7X squared plus 2X squared equal to?
It equals 53X- a number is squared when it is multiplied by itself, so 7X by 7X = 49X. 2X by 2X =4X, so 49X + 4X is 53X.

How do you factor x squared minus 4x minus 5?
Find factors of -5 that can be added to make -4, in this case -5 and 1, so: (x - 5)(x + 1) = x2 - 4x - 5
What is the solution to 4x squared minus x minus 3 equals 0?
4x2 - x - 3 = 0 (x - 1)(4x + 3) = 0 So x - 1 = 0 or 4x + 3 = 0 ie x = 1 or = -3/4 = -0.75

i think its 10
What are the x solutions for the equation 10x2 64 equals 36 plus 6x2?
If the 64 has a minus sign, then the solution is x = +/-5 Simplifying gives 4x squared = 100 ie x squared = 25...
What is the solution for x if sqrt parentheses 4x plus 7 endparentheses minus 4 equals sqrt parentheses 4x minus 1 endparentheses?
sqrt(4x+7) -4 = sqrt(4x-1) squared : (sqrt(4x+7) -4)2 = 4x-1 (4x+7) - 2x4xsqrt(4x+7) +16 = 4x-1 -8xsqrt(4x+7) = -24 sqrt(4x+7) = -24/-8 = 3 squared : 4x+7 = 32 = 9 4x = 9-7 = 2 then x=1/2
What is 7x squared minus 4x minus 5x squared plus 2x?
7x2 -4x -5x2 +2x = 2x2 -2x
