What is the quadratic equation of least degree with zeros at 21 and -24

x^2 +3x -504

Step-by-step explanation:

Sort of do what you'd do to solve but in reverse.  You need 21 for a zero, so the binomial factor would be (x-21) since if you set that  = to zero you'd get 21.  Same for -24.  The binomial factor would be (x+24) since that would give you -24. Now that you have the two binomials, you can just multiply them and get the quadratic. :)
