Question

Use the factorization to find the values of x for which P(x) = 0. (x – 1)(x + 1)(x + 5) = 0 x – 1 = 0, so x = x + 1 = 0, so x = x + 5 = 0, so x =

Answer 1

given (x - 1)(x + 1)(x + 5 ) =0

that is a product of factors equating to zero

to solve equate each factor to zero and solve for x

x - 1 = 0 ⇒ x = 1

x + 1 = 0 ⇒ x = - 1

x + 5 = 0 ⇒ x = - 5
