(x+2)(x^2-8x+15) how do i get the answer to this problem

Hey there!!

Given equation :

... ( x + 2 ) ( x² - 8x + 15 )

Let's solve the equation x² - 8x + 15 first

... x² - 8x + 15

... x² - 3x - 5x + 15

... x ( x - 3 ) - 5 ( x - 3 )

... ( x - 5 ) ( x - 3 )

Hence, the equation we have is :

( x + 2 ) ( x - 5 ) ( x - 3 ) is the final equation.

Hope my answer helps!!
