Przedstaw w jak najprostszej postaci:

a) \ \frac{a^{2}+5ab-b^{2}}{-0,25} \\ b) \ \frac{5(a+b) - (b-a)}{2} \\ c) \ \frac{8a-4(1-a)}{4} \\ d) \ \frac{2(a+b-1)-(a-b)}{3} \\

Zapisz jak najprościej:

a) \ \frac{3a+5a^{2}}{a} \\ b)\ \frac{5ab-2a^{2}}{a} \\ c) \frac{8ab+a(b+3a)}{3a} \\ d) \ \frac{7c^{2}+2x}{0,5c} \\ e) \ \frac{8x(2x+1)-5(x^{2}+2x}{x} \\ f) \ \frac{4x(5x+2y)-4x(5x+2xy)}{xy}
