Quadratic Equations - Exercise 3 - Extracting Square Roots

Fill in the missing justifications for steps below where the equation (2x + 1)² - 3 = 26 is solved
with solutions x = (-1 +/- √29)/2.

STATEMENT

JUSTIFICATION

(2x + 1)² - 3 = 26

(2x + 1)² = 29

2x + 1 = +/- √29

2x = -1 +/- √29

x = (-1 +/- √29) / 2
