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
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
