Identify common factors: Identify common factors in all terms of the polynomial x3−9x2+14x. We can see that each term has an 'x' in it, so we can factor out an 'x' from the polynomial. x(x2−9x+14)
Factor the quadratic expression: Factor the quadratic expression x2−9x+14. We need to find two numbers that multiply to 14 and add up to −9. These numbers are −7 and −2. x(x−7)(x−2)
Check factored form: Check the factored form by expanding it to ensure it matches the original polynomial.x(x−7)(x−2)=x(x2−7x−2x+14)=x(x2−9x+14)=x3−9x2+14xThe expanded form matches the original polynomial, so the factoring is correct.
