What you will learn in this lesson

So far you have solved linear equations, which include constant terms—plain numbers—and terms with the variable raised to the first power, x^1=xx

1

=xx, start superscript, 1, end superscript, equals, x.

You will now learn how to solve quadratic equations, which include terms where the variable is raised to the second power, x^2x

2

x, squared.

Here are a few examples of the types of quadratic equations you will learn to solve:

x^2=36x

2

=36x, squared, equals, 36

(x-2)^2=49(x−2)

2

=49
