Q. Factor out the greatest common factor. If the greatest common factor is 1, just retype the polynomial.6z3−9z2
Identify GCF of terms: Identify the greatest common factor (GCF) of the terms 6z3 and 9z2. The GCF is the highest number and the highest power of z that divides both terms without a remainder.The factors of 6 are 1, 2, 3, and 6. The factors of 9 are 1, 3, and 9. The common factors are 3.Both terms also have a 9z23 term in common.Therefore, the GCF is 9z24.
Find common factors: Divide each term by the GCF to find the remaining factors.For 6z3, divide by 3z2 to get 2z.For 9z2, divide by 3z2 to get 3.
Divide terms by GCF: Write the original polynomial as the product of the GCF and the remaining factors.6z3−9z2=3z2(2z)−3z2(3)Combine the terms inside the parentheses.6z3−9z2=3z2(2z−3)
