Question 1098319
Determine the zeros, the degree, and the leading coefficient to graph this function. 
 f(x) = (x^2 + 2x)(x - 3)
Find the 0's
x^2 + 3x = 0
Factor out x
x(x + 3) = 0
x = 0
and
x = -3
@nd factor
x = 3
The zeros -3, 0, 3
The degree is 3 and leading coefficient is 1 but you can confirm that:
FOIL
(x^2+3x)*(x-3) = x^3 - 3x^2 + 3x^2 - 9x = x^3 - 9x
