3x^2-19x-14
Explanation:
You need to multiply each number in the parenthesis by the other numbers in the parenthesis then combine like terms
(X-7)(3x+2)
3x*x=3x^2
-7*3x=-21x
X*2=2x
-7*2=-14
So you have 3x^2-21x+2x-14
Then you would add -21x+2x and you get -19x
So your final answer would be:
3x^2-19x-14
