Did you find the palette?

Get the roots of this quadratic x^2 + x - 6 = 0.

A quadratic equation is in two variables. y = x^2 + x - 6

Hi chris;

Do you know about the Solve command?

### Re: Teach David

You can use the solve command to solve equations.

``Solve[7x + 7 == 70, x]``

The first part inside the bracket is the equation, then the second part is a variable for which you want to solve.

You can graph it easily:

Plot[3x - 9,{x,-10,10}]

What does this part means? {x,-10,10} x-min and x-max?

How would you graph Shivam's example?

See you later, have a chore. Take a look around in the help in the meantime.
