Question 461958
Multiply and Simplify.Type exponential notation
(64b^2 over 2b^2-12b+18) * (2b-6 over 8b)
..
(64b^2)/ (2b^2-12b+18) * (2b-6)/8b
Simplify by dividing numerator and denominator by 2, so you will be working with smaller numbers.
32b^2/(b^2-6b+9)*(b-3)/4b
32b^2/(b-3)^2*(b-3)/4b  (you should recognize that (b^2-6b+9) is a perfect square=(b-3)^2)
cancelling out 4b and (b-3)
=8b/b-3 (ans)
