You can multiply the brackets to make sure you get 4x² + 4x + 1. Since the numbers in the brackets are the same, we can just use one of them and let it equal to 0. Then solve it. ∴ The answer is x = -1/2.
Step-by-step explanation:
4x2+4x+1=(2x+1)2 or (2x+1)(2x+1)
15 divided by 2 1/2
change 2 1/2 to improper fraction
