Identify quadratic trinomial: Identify the quadratic trinomial and look for common factors.The given expression is 6x2−18x−60. We can see that each term has a common factor of 6.
Factor out common factors: Factor out the greatest common factor (GCF) from each term.The GCF of 6x2, −18x, and −60 is 6. So we factor out 6 from the expression.6(x2−3x−10)
Factor quadratic expression: Factor the quadratic expression inside the parentheses.We need to find two numbers that multiply to −10 (the constant term) and add up to −3 (the coefficient of the x term).The numbers that satisfy these conditions are −5 and +2.
Write factored form: Write the factored form using the numbers found in Step 3.We can now write the quadratic expression as a product of two binomials.6(x−5)(x+2)
Check factored form: Check the factored form by expanding it to ensure it matches the original expression.Expanding 6(x−5)(x+2) gives us:6(x2+2x−5x−10)=6(x2−3x−10)=6x2−18x−60This matches the original expression, so our factoring is correct.
