*In Exercises 33 to 36, solve each incomplete quadratic equation.*

To determine

**To solve:**

The incomplete quadratic equation

Explanation

Solving an equation is to find the value of the unknown variables in the equation, such that the obtained value or values of the unknown should satisfy the equation from which it was derived. Such a value is said to be the solution for the equation. In general a quadratic equation has two solutions for the variable in the equation as the degree of the equation is two.

**Calculation:**

Given,

First look for a common factor (GCF) of the terms

Bur, here the GCF is 1.

Thus, we have

Now, factor the above equation by using the property of the difference of squares of a binomial

Here,

Thus,

By the Zero product property,
