Question

33.14 1(x + 5)³ - (x+1)³ - 4 (3x²-5)+10x-7 2)(x-3)³-x²(x+6)-5x(5-3x)-19x+1 3)(1-3y)³-3(y+3)³+10y(y²-2) 4)(4y-5)³-(4y+5)³-48y(1-10y)+5 -14y²

Answer 1

1)(х+5)^3-(х+1)^3-4(3х^2-5)+10х-7=82х+137
2)(х-3)^3-х^2(х+6)-5х(5-3х)-19х+1= -17х-26
3)(у+4)^3+(3у+1)^3-7у^2(4у+9)+24у^2+8= 57у+73
4)(4у-5)^3-(4у+5)^3-48у(1-10у)+5-14у^2= -48у-245-14у^2
