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!!
