Zad.1 Doprowadz do prostrzej postaci : a] -2a - 3b + 4 (-2a+8b)= b] 2(3ac-8ab+3)-3(ac-4ab)+8= c] x-2(0,3x-ydo potegi drugiej )+(x-0,6y do potegi drugiej ) =

a] -2a - 3b + 4 (-2a+8b)= -2a - 3b -8a+ 32b= -10a+29b b] 2(3ac-8ab+3)-3(ac-4ab)+8=6ac-16ab+6-3ac+12ab = -4ab+3ac+6 c] x-2(0,3x-Y² )+(x-0,6y² ) = x-0,6x+2y²+x-0,6y² = 1,4x+1,4y²

a)-2a-3b-8a+32b=-10a+29b b)6ac-16ab+6-3ac+12ab+8=3ac-4ab+8 c)x-2(0,3x^2+0,18xy^2-xy^2+0,6y^4)=0.3x^4-0,18x^2y^2+0,6xy^4-0,6x^2-0,36xy^2+2xy^2-1,2y^4=
