    But if you can't do this yourself, then what's the point of reviewing.

    all im asking is that do you multiply the numerators by all the denominators eg. (2x - 1) (2x + 5)

    common denominator will be (2x+5)(2x-5)(2x-1) (2x-1)^2-(2x+5)(2x-5)/ (2x+5)(2x-5)(2x-1) 4x^2-4x+1-4x^2+25/(2x+5)(2x-5)(2x-1) 26-4x/(2x+5)(2x-5)(2x-1)

    u hav (2x+5)(2x-5) as the denominator of the 1st part. the common denominator is (2x+5)(2x-5)(2x-1). u havnt nly 2x-1 in the 1st part but which u hav in the common denominator. so multiply the numerator of the 1st nly by 2x-1.

    Now you just need to combine into one fraction keeping the denominator the same

    The final simplification is a mess.
