a) 4(3 - x2) + 4(x-1)2 - 3x(2 - x)+(3 - x)(3 + x)
b) (x-5)2- 3(x - 1)(x+1) - (2x2-1) + x(2x-3)
c) (4 + x)(4 - x) - 2x(1 - 3x)+2(x + 2)2 - 4(x2 - 1)
Pilne Z góry dziękuje musze mieć to jak naj szybciej ;)

a)
4(3-x²)+4(x-1)²-3x(2-x)+(3-x)(3+x) =
= 12-4x²+4(x²-2x+1)-6x+3x²+9-x² =
= 21-2x²-6x+4x²-8x+4 =
= 2x²-14x+25
c)
(4+x)(4-x)-2x(1-3x)+2(x+2²)-4(x²-1) =
= 16-x²-2x+6x²+2x+8-4x²+4 =
= x²+28
d)
(x-5)²+4(x-1)(x+1)-(2x²-1)+x(2x-3) =
= x²-10x+25+4(x²-1)-2x²+1+2x²-3x =
= x²-13x+26+4x²-4 =
= 5x²-13x+22
