Write the quadratic equation whose roots are 3 and -6, and whose leading coefficient is 3.
(use the letter x to represent the variable.)

Step-by-step explanation:

if the roots are 3 and -6, we can start with:

But the leading coefficient must be 3, we just add a 3 to one of the x's:

But now we have to make sure the roots work again:

So our equation is:

the roots are ( x-intercepts) x=-0.5,x=1,x=3

the y-intercept is the point (0,3)
