Question

Find the equation for a parabola that has zeros at - 6 and 4 and passes through the point (2,-48). Type the value of "a" (the leading coefficient) in the box below.

Answer 1

the simplest equation with zeros at -6 and 4 is
(x+6)(x-4)
when x = 2 this equals -16
givibg a factor of -48/-16 = 5

reqd equn. is 3(x+6)(x-4) = 0

Answer 2

sorry:
-48/-16 = 3
