25 pts


FOLLOW the process of COMPLETING THE SQUARE to solve x^2 - 10x + 8 = 0.

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

only existing answer options:

(x - 10)^2

(x - 20)^2

(2x - 10)^2

btw sorry if it isn’t actually 25 points because I tried to give 25 pts in my last question but it only said 13 idk how brainly works :/

AND
if you can, please explain the answer

Respuesta :

 - 10x + 8 = 0

x
² -10x + 5² -5² + 8 = 0

(x - 5)² - 25 + 8 = 0

(x - 5)² - 17 = 0

(x - 5)² = 17     ← Equation: LHS = (x - 5)²

x - 5 = ±√17

x= √17 + 5 or x = -√17 + 5

x = 9.12 or 0.88

Answer: x = 9.12 or 0.88
x= 9.12 im pretty sure
