Identify Common Factor: Identify the common factor in all terms.The expression is x2(x+3)−7x(x+3)+6(x+3). Each term contains the factor (x+3).
Factor Out Common Factor: Factor out the common factor (x+3). We can write the expression as (x+3)(x2−7x+6).
Factor Quadratic Expression: Factor the quadratic expression.The quadratic expression x2−7x+6 can be factored into (x−1)(x−6) because (x−1)(x−6)=x2−6x−x+6=x2−7x+6.
Write Completely Factored Form: Write the completely factored form.The completely factored form of the original expression is (x+3)(x−1)(x−6).
