8x2 + 16x + 8 = 0

x=5

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

8x2 + 16x + 8 = 8*(x2 + 2x + 1) = 8*(x + 1)2

8x2-2x-15 = 0 (2x-3)(4x+5) = 0 x = 3/2 or x = -5/4

8x2 + 16x + 8 = 0

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

x=5

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

8x2 + 16x + 8 = 8*(x2 + 2x + 1) = 8*(x + 1)2

(x2 + 4 - 2sqrt(3)) (x2 + 4 + 2sqrt(3))

16.

15 = 8x2 - 14x; whence, 8x2 - 14x - 15 = (2x - 5)(4x + 3) = 0. Therefore, x = 5/2 or -3/4.

4

(4x + 3)(2x - 1) so x = -0.75 or 0.5

8x2-2x-15 = 0 (2x-3)(4x+5) = 0 x = 3/2 or x = -5/4

(2x - 8)(-4x + 4) = -8x2 + 40x - 32
