Exercise 17 Page 86

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

0, 14

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

y(y-14)=0

Use the Zero Product Property

lcy=0 & (I) y-14=0 & (II)

(II): LHS+14=RHS+14

ly_1=0 y_2=14

We found that the solutions to the given equation are y=0 and y=14. To check our answer, we will graph the given function y=x(x-14) using a calculator. Note that in the calculator we will use the variable x instead of y.

We can see that the x-intercepts are 0 and 14. Therefore, the solutions are correct.
