9) If x=-4 is a zero of a polynomial p(x), then the zero of p(x² - 6x + 5) is​
spin [16.1K]

If x=-4 is a zero of p(x), then we can write

p(x) = (x + 4) q(x)

for another polynomial q(x).

Note that x^2 - 6x + 5 = (x - 5)(x - 1). Then

p(x^2 - 6x + 5) = p\bigg((x-5)(x-1)\bigg) \\\\ ~~~~~~~~~~~~ = ((x - 5)(x-1) + 4) q\bigg((x-5)(x-1)\bigg) \\\\ ~~~~~~~~~~~~ = (x^2 - 6x + 9) q(x^2 - 6x + 5) \\\\ ~~~~~~~~~~~~ = (x - 3)^2 q(x^2 - 6x + 5)

so that \boxed{x = 3} is a root of p(x^2 - 6x + 5).
