Question

Solve for x. Enter the solutions from least to greatest.

(x - 10)² - 1 = 0
lesser x =
greater x =

Answer 1

lesser x = 9

greater x = 11

Explanation:

(x-10)² - 1 = 0

(x-10)² = 1

(x-10) = +- root1 (positive and negative root1)

So (x-10) = +1 and (x-10) = -1

Firstly

X - 10 = 1

X = 11

Secondly

X - 10 = -1

X = 9

So you have x = 9, and x = 11

The smaller one is the lesser x (9)

The larger one is the greater x (11)
