Solving Quadratic Equations
A quadratic equation is an equation that could be written as
ax 2 + bx + c = 0
when a 0.
There are three basic methods for solving quadratic equations: factoring, using the quadratic formula, and completing the square.
Factoring
To solve a quadratic equation by factoring,
Put all terms on one side of the equal sign, leaving zero on the other side.
Factor.(x-8)(x-2)=0
Set each factor equal to zero.
Solve each of these equations.
Check by inserting your answer in the original equation.
Example 1
Solve x 2 – 6 x = 16.
Following the steps,
x 2 – 6 x = 16 becomes x 2 – 6 x – 16 = 0
Factor.
( x – 8)( x + 2) = 0
Setting each factor to zero,
x-8=0 x-2=0
x=8 x=-2
Both values, 8 and –2, are solutions to the
