Q. Factor out the greatest common factor. If the greatest common factor is 1, just retype the polynomial.2z3−10z2
Identify GCF: Identify the greatest common factor (GCF) of the terms 2z3 and 10z2. The GCF is the highest number that divides both coefficients (2 and 10) and the highest power of z that is in both terms.The coefficients 2 and 10 have a GCF of 2. The variable part, z3 and z2, have a GCF of z2 since that is the highest power of z that both terms share.
Write Terms as Product: Write each term as a product of the GCF and the remaining factors.For 2z3, the GCF is 2z2, so the remaining factor is z. Therefore, 2z3 can be written as 2z2×z.For 10z2, the GCF is 2z2, so the remaining factor is 5. Therefore, 10z2 can be written as 2z2×5.
Factor Out GCF: Factor out the GCF from the polynomial 2z3−10z2. Using the expressions from the previous step, we can write the polynomial as: 2z3−10z2=2z2⋅z−2z2⋅5 Now, factor out the GCF, 2z2, from both terms: 2z3−10z2=2z2(z−5)
