Question

P(x) = (x + 2)(2x^2+ 3x – 9)

Plot all the zeros (c-intercepts) of the polynomial in the interactive graph.

Answer 1

-2, -3, 3/2

Explanation:

Factor 2x^2+ 3x – 9

(x+3)(2x-3)

(x + 2)(x+3)(2x-3) - the zeros are basically the opposite of the numbers here

x+2=0

x=-2

x+3=0

x=-3

2x-3=0

x=3/2

To plot just put the numbers on the x line because it is (x,0)
