(x^2+2x)/(4x+8)= ?

and

reduce:

(8a^3*b*a^-2)/(2b)^2= ?

First. In the numerator, factor out an x. In the denominator, factor out a 4. this will leave a common factor that can be divided out.

Second.change the numerator to 8ab. Check that to see if it is right.

change the denominator to 4b^2

now you have 8ab/4b^2 reduce the 8/4, and the b/ b^2

1) ánswer X/8

2) answer:2ab

or wrong?
