this question did by quadratic formula means x = -b ± √b^ - 4ac / 2a by this formula first arrange the equation -5 x^ + 7 -2 and
a = -5
b = 7
C = -2
after that substitute in the formula
Answer:
9(2p-4)
Step-by-step explanation:
To factor an expression, find the GCF of each term. 18p and 36 share in common the factor 9. Divide each term by 9 to get the factor.
18p - 36 = 9(2p-4)
