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