Answer:
The correct answer is c) -7/2
Step-by-step explanation:
To find the answer to this, start by factoring the equation into two parenthesis.
4x^2 + 28x + 49
(2x + 7)(2x + 7)
Now that we have the parenthesis, and we can see they are the same, we simply need to set one of them equal to 0 and solve.
2x + 7 = 0
2x = -7
x = -7/2
