How do you factor completely #16b^3 + 8b#?

Answer 1

#8b(2b^2+1)#

You can factor an #8# and a #b# out of both terms by finding the LCM (Least Common Factor) of #16# and #8# and #b^3# and #b#.

To factor completely the expression 16b^3 + 8b, first factor out the greatest common factor, which is 8b. After factoring out 8b, you get 8b(2b^2 + 1). The expression 2b^2 + 1 is a sum of squares, and it cannot be factored further using real numbers. So, the factored form of the expression 16b^3 + 8b completely is 8b(2b^2 + 1).
