In Exercises 33 to 36, solve each incomplete quadratic equation. 2 x 2 - 6 x = 0

To determine

To solve:

The incomplete quadratic equation.

2x2-6x=0

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,

2x2-6x=0

First look for a common factor (GCF) of the terms 2x2, -6x.

 Terms Prime factors 2x2−6x 2⋅x⋅x−⋅3⋅2⋅x

Here, the GCF is 2ċx=2x.

Thus, the given equation from become

2xċx-2xċ3=0

Here, 2x is distributed over (x-3) thus, by the reverse of the distributive property o
