Answer:

See full factoring process below:

Explanation:

First, we can factor #color(red)(-3x)# from the right side of the equation:

#y = (color(red)(-3x) xx x^2) + (color(red)(-3x) xx x) - (color(red)(-3x) xx 20)#

#y = color(red)(-3x)(x^2 + x - 20)#

Now to complete the factoring we can factor the quadratic within the parenthesis:

#y = -3x(x + 5)(x - 4)#
