Answer:
30°
Step-by-step explanation:
180-75-75=30
So,
First, we find the prime factored form (P.F.F.) of 65 and 91.
P.F.F. of 65: 5 * 13
P.F.F. of 91: 7 * 13
Find the common numbers
13
13 = G.C.F.
Note: This method works for finding any G.C.F. (find common primes)
Here:
=(2x+3)(x-6)
=2x²-12x+3x-18
=2x²-9x-18
So the answer is (2x+3)(x-6)
