Answer:
c
Step-by-step explanation:
x^2+5x-14
factor by finding multiples of (-14) that add up to 5
7*-2=-14
7+-2=5
So the factored out equation is (x+7)(x-2)
Therefore the solutions are x=-7 and x=2

Dont know how to explain but this is the answer
Answer:
10x² + 6x + 3xy + 3y - y²
Step-by-step explanation:
Each term in the second factor is multiplied by each term in the first factor, as shown
(2x + y)(5x - y + 3)
= 2x(5x - y + 3) + y(5x - y + 3) ← distributing
= 10x² - 2xy + 6x + 5xy - y² + 3y ( collect like terms )
= 10x² + 6x + 3xy + 3y - y²
Answer:
-50x - 66
