1. Zredukuj wyrazy podobne a) b+a+r+b+a+p+a+p+a b) b-a-r-b-a-p-a-p-a c) a+2b+3c-4c-5b-6a d) a3 (do sześcianu)= a3+2a-a2+3a2-10a3+5 e) 5x2-x2+y2+y-3-y+(-2)y2+5 f) 13x+7y-10x-4y+5y g) 90x+3y-x2-9* 9x- 2y+x2 * (razy)

a) b+a+r+b+a+p+a+p+a = 2b+4a+r+2p b) b-a-r-b-a-p-a-p-a = -4a-r-2p c) a+2b+3c-4c-5b-6a = -5a-3b-c d) a3+2a-a2+3a2-10a3+5 = -9a3+2a+2a2+5 e) 5x2-x2+y2+y-3-y+(-2)y2+5 = 4x2-y2+2 f) 13x+7y-10x-4y+5y = 3x+8y g) 90x+3y-x2-9* 9x- 2y+x2 = 9x+y

a) b+a+r+b+a+p+a+p+a 4a+2b+r+ 2p b) b-a-r-b-a-p-a-p-a -4a-r-2p c) a+2b+3c-4c-5b-6a -5a-3b-c f) 13x+7y-10x-4y+5y 3x8y g) 90x+3y-x2-9* 9x- 2y+x2 90x + 3y-x2 - 81x - 2 +x2 11x+ 3y-2 Tyle potrafie :)
