Follow the process of completing the square to solve x2 - 10x + 8 = 0.

How will the left side of the equation factor in step 5?

(x - 10)^{2}

(x - 20)^{2}

(2x - 10)^{2}

Follow the process of completing the square to solve 2x2 + 8x - 12 = 0.

How will the left side of the equation factor in step 5?

(2x + 32)^{2}

(4x + 8)^{2}

(4x + 16)^{2}

x^2+10x+8=0

move 8 to the right by subtracting 8 from both sides.

x^2+10x=-8

b/2 10/2 =5

5^2 =25

add 35 to both sides

x^2+10x+25=-8+25

(x+5)^2=17

x+5=+- (root)17

x=-5+-(root)17
