Answer: (r + 4)(r + 8)
Alright, I would first rearrange the equation by bringing all your terms to one side by adding 12r and 32 to both sides. This will result in the rearranged equation:
You can then factor the equation into the two binomials: (r + 4)(r + 8).
4 + 8 equals the b term, 12, and 4 x 8 equals the c term, 32.
