Exercise 18 Page 86

To solve this equation, we will apply the Zero Product Property.

- 6, 0

The equation is a factored polynomial, therefore we will apply the Zero Product Property to solve it.

3x(x+6)=0

Use the Zero Product Property

lc3x=0 & (I) x+6=0 & (II)

(I): .LHS /3.=.RHS /3.

lx=0 x+6=0

(II): LHS-6=RHS-6

lx_1=0 x_2=- 6

We found that the solutions to the given equation are x=0 and x=- 6. To check our answer, we will graph the given function y=3x(x+6) using a calculator.

We can see that the x-intercepts are - 6 and 0. Therefore, are solutions are correct.
