Answer:
x = 3/2
or
x = (-5)/2
Explanation:
(2x+1)^2 = 16 find x
(2x + 1)² = 16
4x² + 4x + 1 = 16
4x² + 4x − 15 = 0
(2x − 3)(2x + 5) = 0
2x − 3 = 0
x = 3/2
or
x = (-5)/2
--------------------------------------
(2 × 3/2 + 1)² = 16
(3 + 1)² = 16
4² = 16
16 = 16 the answer is good
(2 × (-5)/2 + 1)² = 16
-4² = 16
16 = 16 the answer is good
