asked • 10/24/20The polynomial of degree 3, P(x), has a root of multiplicity 2 at x=2 and a root of multiplicity 1 at x=−3. The y-intercept is y=−2.4.Find a formula for P(x).

Math, microeconomics or criminal justice
y = a(x-2)^2(x+3)
-2.4 =a(4)(3)
a = -2.4/12 = -.2
p(x) = -.2(x-2)^2(x+3)
= -(x^2 -4x +4)(x+3)/5
= - (x^3)/5 + (x^2)/5 +8x/5 +12/5
= -,2x^3 + .2x^2 + 1.6x + 2.4
