Question

sprowadź do najprostrzej postaci Z GÓRY WIELKIE DZIĘKI

(3x+2)do kwadratu+(1-2x)(1+2x)=

(x+y)(4x-y)-(2x-y)=

(x-3)(xdo kwadratu-3x-9)-(xdo3+27)=

(x+2)do3-x(xdo kwadratu-5)+(x-1)do kwadratu=

Answer 1

(3x+2)²+(1-2x)(1+2x)=9x²+12x+4+1-4x²=5x²+12x+5

(x+y)(4x-y)-(2x-y)=4x²+3xy-y²-2x+y=4x²-y²+3xy+y

(x-3)(x²-3x-9)-(x³+27)=x³-3x²-9-3x²+9x+27-x³-27=-6x²+9x-9

(x+2)³-x(x²-5)+(x-1)²=x³+6x²+12x+8-x³+5x+x²-2x+1=7x²+15x+9
