Step-by-step explanation:
2x2+15x+7
For a polynomial of the form ax2+bx+c
, rewrite the middle term as a sum of two terms whose product is a⋅c=2⋅7=14 and whose sum is b=15

x(2x+1)+7(2x+1)
Factor the polynomial by factoring out the greatest common factor, 2x+1
.
(2x+1)(x+7)
Answer:
I think its flat sorry if it's wrong
Answer:
s = 15 over 2 (15/2 fraction) or 7.5
The answer is 1952 because you have to add all of the numbers together
