Answer 1

$1)...=frac{b+d}{4(b+d)}-frac{b+2d}{2d-5b}=frac{1}{4}-frac{b+2d}{2d-5b}=frac{2d-5b-4b-8d}{4(2d-5b}=frac{-6d-9b}{4(2d-5b)}=frac{-3(2d+3b)}{4(2d-5b)}}\2)...=frac{(3x-6a)(4x-3a)+(a+4x)(4a+4x)}{4(a+x)(4x-3a)}=\=frac{12x^2-9ax-24ax+18a^2+4a^2+16ax+4ax+16x^2}{4(a+x)(4x-3a)}=frac{28x^2+22a^2-13ax}{4(a+x)(4x-3a)}$
