[latex]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)}[/latex]
