Answer: (x-1)(3x+8)

Step-by-step explanation:

Slide and divide method

See what multiplies to get -24 (because of 3 and -8) and what adds to get 5

Put those into factoring form (x-3)(x+8) without a number in front of the x’s

Divide the numbers by what isn’t in front of the x’s (-3/3 and 8/3)

Simplify them and if it doesn’t divide perfectly, put the denominator in front of the x

Solution

**I can’t explain it well but watch a video on the method AND ONLY DO IT IF IT WORKS WELL FOR YOU**
