The polynomial of degree 3, P(x), has a root of multiplicity 2 at x=1 and a root of multiplicity 1 at x=−3. The y-intercept is y=−0.3
find formula for P(x)
This is the answer
(x) = a(x - 2)2(x + 5), a ≠ 0
Use the given point (0,-10) to find a.
-10 = a(0 - 2)2(0 + 5) = a(4)(5) = 20a
a = -10/20 = -1/2
P(x) = (-1/2)(x - 2)2(x + 5)
