the quadratic equation whose roots are
x%5B1%5D=-4 and x%5B2%5D=6, and whose leading coefficient is a=2

f%28x%29=a%28x-x%5B1%5D%29%28x-x%5B2%5D%29.....plug in given values
f%28x%29=2%28x-%28-4%29%29%28x-6%29
f%28x%29=2%28x%2B4%29%28x-6%29
f%28x%29=2%28x%5E2-6x%2B4x-24%29
f%28x%29=2%28x%5E2-2x-24%29
f%28x%29=2x%5E2-4x-48%29
