Answer 1

Ответ:

a) x²/x-6  -  36/x-6 = x²-36/x-6 = (x-6)·(x+6)/x-6 = x+6

б) 2/a - 3/a² + 1/a³ = a²·2/a²·a - a·3/a·a² + 1/a³ = 2a²/a³ - 3a/a³ + 1/a³ = 2a²-3a+1/a³ = 2a²-3a+1/a³

в) c/(a+b) - 2c/5(b+a) = 3c/5(a+b) = 3c/5a+5b

г) b²/ba+a² - a/b+a = b²/a(b+a)  -  a/b+a = b²-a²/a(b+a) = (b-a)(b+a)/a(b+a) = b-a/a

д) p + 4/p-2 + 3 = p(p-2)+4+3(p-2)/p-2 = p²-2p+4+3p-6/p-2 = p²+p-2/p-2
