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) √°nswer X/8

2) answer:2ab

or wrong?

    6-y --------- y^2-27-24 well it should simplify to (6-y)/(y^-1) which then changes to y(6-y) which then equals y(6-y)=0 then you set both parts equal to zero and solve for xero y=0 and/or (6-y)=0 so y=0 or y=6 Did you mean for this …

    How do you do?: x^2+1 ----- x^4-1 Thanks! Try to factor wherever you can so you can reduce as much as you can. Factors of x^4 - 1 are (x^2 + 1)(x^2 - 1). Now we have: x^2 + 1 ------------------ (x^2 + 1)(x^2 - 1) Do you see a common
