Question

Sprowadź do jak najprostszej postaci.

Answer 1

1.[3x(x+y):(x²-2xy+y²)]*[2y(x-y):(x²+2xy-y²)]=[4x+3xy:x²-2xy+y²]*[2xy-2y²:x²+2xy-y²]=

[3x(x+3y):(x²-2xy+y²)]*[2y(x-y):(x²+2xy-y²)]

2. [(m²+2mn-n²):(5m²+5mn)]*[(2n³-2n³)/15m²]=[(m²+2mn-n²):5m(m+n)]*[0:15m²]

3.[x(x-1):(xy)]*[x(x+y²):(x²-y²)]=[x:xy]*[x(x+y²):(x-y)]

4.[(x-4)(x+4):(-x)]:[6x:(x-3)(x+3)]
