8x2 + 16x + 8 = 0

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.

Y=(x+8)^2-5

You can't solve it. But you can simplify it to get: 4x+y=2

It is: 25-4(8*6) = -167

8x2-16x+8=8(x-1)2 How to do it: First factor out the 8 and you have 8(x2 -2x+1) look at the 1 and not the only two way to get 1 are by multiplying -1x-1 or 1x1 Only the -1x-1 will work and give us the -2x.

8-8x=8x+18 Through simple algebra, this can be manipulated to solve for x: 8=16x+18 -10=16x -5/8=x

a=64 b=8 (x+16x+64)=(x+8)^2

Half of the coefficient of x, squared. For example: x2 + 16x -3 you would add 8^2. Then you would have: x2 +16x +8^2 = 3-8^2 Which leads to: (x+8)^2 = -61

x= 2 because 2x+4=16 4x2=8 8+2 or 8x2=16

8 and 2 8x2=16

x2 - 16x + 68 = 5 (x - 8)2 + 4 = 5 (x - 8)2 = 1 x - 8 = 1 or -1 x = 9 or 7
