Identify Common Factor: Identify the common factor in both terms.The expression is 3x2(3x−5)+4(3x−5). Both terms have a common factor of (3x−5).
Factor Out Common Factor: Factor out the common factor (3x−5). We can write the expression as (3x−5)(3x2+4) by factoring out (3x−5).
Check Quadratic Expression: Check if the remaining quadratic expression can be factored further.The quadratic expression 3x2+4 does not factor further over the integers because it does not have real roots. The discriminant b2−4ac=02−4(3)(4)=−48 is negative.
Write Final Factored Form: Write the final factored form of the expression.The completely factored form of the expression is (3x−5)(3x2+4).
