Q. Factor out the greatest common factor. If the greatest common factor is 1, just retype the polynomial.10z3−8z2
Find GCF Factors: We need to find the greatest common factor (GCF) of the terms 10z3 and 8z2. To do this, we will list the factors of the coefficients and the powers of z.Factors of 10: 1, 2, 5, 10Factors of 8: 1, 2, 8z21, 8The common factors of the coefficients are 1 and 2.For the variable z, since both terms have at least 8z26, we can take 8z26 as a common factor.The GCF of 10z3 and 8z2 is therefore z0.
Identify Common Factors: Now we will divide each term by the GCF to factor it out.For the first term, 10z3 divided by 2z2 is 5z.For the second term, 8z2 divided by 2z2 is 4.So, the polynomial factored by the GCF is 2z2(5z−4).
