Question

Write the quadratic equation whose roots are -6 and -4, and whose leading coefficient is 3

Answer 1

See my other comment just that this time we have an additional factor for the leading coeffiecient (the coefficient at the largest monome, in this case x^2)

p(x) = 3 * (x-(-6))* ( x-(-4))= 3 * (x^2 +10x +24)

p(x) = 3x^2 + 30x + 72
