Which of the following are solutions to the equation below? check all that apply. 4x^2 + 12x + 9 = 25

x = 1 or -4

Step-by-step explanation:

4x² + 12x + 9 = 25

4x² +12x + 9 - 25 = 0

4x² + 12x - 16 = 0

Dividing by 4 throughout gives;

x² + 3x - 4 = 0

Applying the quadratic formula you get;

x = 1 or -4

just find the gcf and solve the gcf's until you get each answer i have a really good feeling somethings missing xd (like the dimensions of the fence) *cough *cough *hint *hint

step-by-step explanation:

the answer is 99.
