Question

Find nth degree polynomial function with real coefficients satisfying the giving conditions.            N=3;-5 and i are zeros; f(-3)=60

Mark M. · Accepted Answer

f(x) = a(x + 5)(x - i)(x + i)f(x) = a(x + 5)(x2 + 1)f(x) = a(x3 + 5x2 + x + 5)60 = a((-3)3 + 5(-3)2 + (-3) + 5)Can you solve for a and answer?
