Quadratic Equation

A quadratic equation is any equation that can be rearranged in standard form as

ax^2+bx+c=0

where a, b and c are numbers and

a\ne0

Multiple Select

Which of the following are quadratic equations?

$2x+5=7$

$x^2+5x-24=0$

$2x^2-5=11$

Solving Quadratic Equations

There are lots of different methods to find the roots of a quadratic equation. Here are a few:

-Trial and error

-Factoring

-Completing the square

-Quadratic formula

Multiple Choice

Solve this quadratic equation by factoring:

0=x^2+6x-16

$x=2,\ x=8$

$x=-2,\ x=-8$

$x=-2,\ x=8$

$x=2,\ x=-8$

Type answer...

The Discriminant

The discriminant is part of the quadratic formula. It tells you how many roots a quadratic equation has.

Fill in the Blanks

What is the value of the discriminant of this quadratic equation? $2x^2-6x+3=0$

Type answer...

Fill in the Blanks

Use the discriminant to determine the number of roots for this quadratic equation: $x^2-6x+9=0$

Type answer...

Open Ended

Mrs. Deveaux said that she hurt her foot when a trailer hitch fell on it... boring.
