How to solve a quadratic equation with your GDC

If you're stuck on working out quadratic equations, and have a graphing calculator on hand, this method is perfect for you!

Lets use this example: x^2 + 6x+8 

Switch on your GDC and go to the option 'Equation'.

You then want to select 'Polynomial'.

Select a degree of '2' because in the example, it is x^2

Then fill in the blanks in order
so,

a = 1
b = 6
c = 8

Click solve....
and you should have your answer.

So x = -2 or x = -4.
