Exercise 54 Page 767

Use the Zero Product Property.

0, - 5

Practice makes perfect

To solve the given equation, let's factor and solve using the Zero Product Property.

Factoring

Let's get factoring!

3x^2+15x=0

Factor out 3x

3x(x+5)=0

Solving

Now we can apply the Zero Product Property to solve.

3x(x+5)=0

Use the Zero Product Property

lc3x=0 & (I) x+5=0 & (II)

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

lx=0 x+5=0

(II): LHS-5=RHS-5

lx_1=0 x_2=- 5

The solutions for our equation are 0 and - 5.
