What are the solutions to the quadratic equation 4 times open paren x plus 2 close paren squared is equal to 36 ?

Divide both sides by 4 to get (x + 2)² = 9. Taking the positive and negative square roots gives x + 2 = 3 or x + 2 = −3, so x = 1 or x = −5. Therefore, the correct choice is A: x = −5 and x = 1.
