Shorten fraction:
(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?
