Step-by-step explanation:
Hello!!!
(3x+2)(x-7)
This type of math, we can use the FOIL method (First Outer Inner Last).
The foil method is (a+b)(c+d) = ac + ad + bc + bd
So: (3x+2)(x-7) = 3x * x, + 3x * (-7), + 2 * x, + 2 * (-7)
We can simplify to: 3x^2 -21x + 2x -14; btw, ^ is squared so, x^2, is x squared
Then we can add -21x and 2x because they are like terms:
3x^2 - 19x - 14
