Q. Factor out the greatest common factor. If the greatest common factor is 1, just retype the polynomial.2r3−6r
Find GCF of Terms: We need to find the greatest common factor (GCF) of the terms 2r3 and −6r. To do this, we look for the highest power of r that is common to both terms and the largest number that divides both coefficients.
GCF of Coefficients: The GCF of the coefficients 2 and −6 is 2 since 2 is the largest number that divides both 2 and 6.
GCF of Variables: The GCF of the variables r3 and r is r, since r is the highest power of r that is common to both terms (r1 is contained in r3).
Combine Coefficients and Variables: Combining the GCF of the coefficients and the variables, we get the GCF of 2r3 and −6r to be 2r.
Divide Each Term by GCF: Now we divide each term by the GCF to factor it out:2r3÷2r=r2−6r÷2r=−3
Write Original Polynomial with GCF Factored Out: Writing the original polynomial with the GCF factored out, we get: 2r3−6r=2r(r2−3)
