Identify common factor: Identify the common factor in all terms of the expression.The common factor is (x2−10).Factor out the common factor from the expression.x2(x2−10)−5x(x2−10)−24(x2−10)=(x2−10)(x2−5x−24)
Factor out common factor: Now, factor the quadratic expression x2−5x−24. To factor the quadratic, we look for two numbers that multiply to −24 and add to −5. The numbers −8 and 3 satisfy these conditions. So, we can write x2−5x−24 as (x−8)(x+3).
Factor quadratic expression: Combine the factored quadratic with the common factor that was factored out earlier.The completely factored form of the expression is (x2−10)(x−8)(x+3).
