A quadratic equation is an equation that has x^2 power in it. So the highest power of a quadratic equation is 2

'; explain[1] = '#2

The standard form of a quadratic equation is ax^2 + bx +c. Which gives us 3 terms to work with.

'; explain[2] = '#3

The quadratic formula uses the standard form of quadratic equations, defined as ax^2 + bx +c. The values of a, b and c are used to solve the equation.

'; explain[3] = '#4

An equation with a power of 4 can often be FOILed and you can then solve each binomial and get your answers for the equation. So it is possible to use quadratic methods on an equation with a power of 4.

'; explain[4] = '#5

After solving a quadratic equation, you almost always have 2 answers.
