Best Answer

This is an example of a quadratic equation. It has many solutions depending of the value of x. Its solution would commonly be shown as a graph.

For example, if x = 2 then the answer is 22 + 16x2 +55 = 4+32+55 = 91.

if x = 3 then the answer is 32 + 16x3 + 55 = 9+48+55 = 112.

[but check my arithmetic!]

Q: X to the second power plus 16x plus 55 equals?

8x2 + 16x + 8 = 0

The Commutative Property of Addition.

16x + 2 - 8 = 16x + 24 implies 16x - 6 = 16x + 24 subtracting 16x from both sides, this implies: -6 = 24 So the equation has no soultions.

5x2-16x+12 = (5x-6)(x-2) when factored with the help of the quadratic equation formula

16x-8x+12 = 78+22 16x-8x = 78+22-12 8x = 88 x = 11

Combining like terms, 16x + 20 = 180 or 16x = 160 so that x = 10

Assuming you wish to make this equation equal zero, for x2 + 16x + 55 = 0, x = -5.

4(1-4x+7y)

Y=(x+8)^2-5

If your function is 4x^2+16x+16=0 then x=-2, if it is 4x^2-16x+16=0, then x=2
