Identify Common Factors: Look for common factors in the first two terms and the last two terms separately.For the first two terms, 4n3 and −16n2, the common factor is 4n2.For the last two terms, 3n and −12, the common factor is 3.
Factor Out Common Factors: Factor out the common factors from the first two terms and the last two terms.4n3−16n2=4n2(n−4)3n−12=3(n−4)
Write Factored Expression: Write the expression with the factored terms. 4n3−16n2+3n−12=4n2(n−4)+3(n−4)
Factor Out Binomial Factor: Factor out the common binomial factor (n−4).4n2(n−4)+3(n−4)=(4n2+3)(n−4)
