I assume you're solving for x in the following equation:
4x2 - 32 = 4
To find the solution, start by adding 32 to both sides, so that the constant is on the right:
4x2 = 36
Next, divide both sides by 4, so you have x alone on the left side:
x2 = 9
So, x is going to be the square root of 9. Since x2 = (-x)2, there are two solutions: one positive, and one negative. 3 squared equals 9, so the two answers are -3 and 3.

What is 7x squared minus 4x minus 5x squared plus 2x?
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 the solution to 4x squared minus x minus 5 equals 0?
4x2 - x - 5 = 0 4x2 + 4x - 5x - 5 = 0 4x(x + 1) - 5(x + 1) = 0 (4x - 5)(x + 1) = 0 4x - 5 = 0 or x + 1 = 0 4x = 5 or x = -1 x = 5/4 o x = -1
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.
What is 4x minus 7 equals 5 plus 7x?
4x - 7 = 5 + 7x x = -4
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

(4x2) (x/4)(8x - 32) =x3(8x - 32) = 8x3(x - 4)
How do you factor x squared minus 4x minus 21?
x2 - 4x - 21 = (x-7)(x+3)
Can you solve x squared minus 4x minus 2 equals 0?
Yes and x = 2+square root of 6 or x = 2-square root of 6
How do you factor 16x squared?
4x times 4x equals 16x2.
4x squared minus twenty equals zero?

What is the mistake in this solving of an equation 3x minus 12 equals 10x minus 15 minus 6x minus 10 3x minus 12 equals 4x minus 25 3x plus 13 equals 4x 13 equals x?
3x - 12 = 10x - 15 - 6x -10 3x - 12 = 4x -25 3x + 13 = 4x 13 = 4x - 3x 13 = x None?
