1. Solving Quadratic Equations by Factoring

Continue to next subchapter

Exercise 37 Page 174

Use the Zero Product Property.

x=0 and x=9

Practice makes perfect

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

Factoring

Let's get factoring!

12x^2-108x=0

Factor out 12x

12x(x-9)=0

Solving

Now we can apply the Zero Product Property to solve.

12x(x-9)=0

Use the Zero Product Property

lc12x=0 & (I) x-9=0 & (II)

(I): .LHS /12.=.RHS /12.

lx=0 x-9=0

(II): LHS+9=RHS+9

lx_1=0 x_2=9

The solutions for our equation are 0 and 9.
