What are the two solutions of the equation x^2 − 10 = 90 ?
Show work :)

x = 5 ±√115

Step-by-step explanation:

x² - 10x - 90 = 0

You can solve for x by doing it in 2 ways: Completing the square and by using the quadratic formula

Completing the Square

(x² - 10x + 25) - 25 - 90 = 0

(x - 5)² - 115 = 0

(x - 5)² = 115

x - 5 = ±√115

x = 5 ±√115

Quadratic Formula

√460 = √4 X √115

Hence 2√115
