Answer 10

Maybe the best way to prove this is just to multiply (3x+2) times (x-5). We would use the FOIL method, which stands for First, Outer, Inner, Last. Here are the steps:

1. multiply the first, meaning the 3x times the x. This gives us 3x^2.

2. Multiply the outer, which means the 3X times the -5. This gives us -15x.

3. Multiply the inner, which means the 2 times the X. This gives us 2X.

4. multiply the last, meaning the 2 times the -5, giving us -10.

Putting it all together, we have:

3x^2 -15X +2X -10, or 3x^2-13X-10.

FACTORING POLYNOMIALS

Factoring a polynomial is the opposite process of multiplying polynomials. Recall that when we factor a number, we are looking for prime factors that multiply together to give the number; for example

6 = 2 × 3 , or 12 = 2 × 2 × 3.

When we factor a polynomial, we are looking for simpler polynomials that can be multiplied together to give us the polynomial that we started with. You might want to review multiplying polynomials if you are not completely clear on how that works.

When we factor a polynomial, we are usually only interested in breaking it down into polynomials that have integer coefficients and constants.
