Respuesta :

First factor out the 5.
5(x^2-6x+8)
Then factor the smaller polynomial.
5(x-4)(x+2)
Then using zero product law, find the roots/zeros/x-intercepts.
x-4=0
x= 4
And
x+2=0
x= -2

First factories the polynomials.
After that equate the factors to 0 and find the values of x
In this case it is
x = 4 & x = 2
Then find f(4) & f(2)
