Zapisz w jak najprostszej postaci: a). 2(3x-2y+3z)-5(x-y-z)= b). 4x(x-y-z)-2x(4x-y+z)= c). -3x²(x-⅔y)+5x(x²-7xy)= d). -2√2(a+√2b)-4(a√2-2b)= Wielkie Dzięki .!

a). 6x - 4y + 6z -5x + 5y + 5z = x + y + 11z b). 4x² - 4xy - 4xz - 8x² + 2xy - 2xz = -4x² - 2xy - 6xz c). -3x³ +2x²y + 5x³ - 35x³y = 2x³ + 2x²y - 35x³y d). -2a√2 - 2b√4 - 4a√2 + 8b = -8a√2 + 4b

A) 2(3x-2y+3z)-5 (x-y-z) = 6x-4y+6z - 5x +5y+5z = x+y+11z B) 4x (x-y-z) - 2x(4x-y+z) = 4x² - 4xy - 4xz -8x² + 2xy - 2xz= -4x² - 2xy - 6xz C) -3x² ( x - ⅔y) + 5x (x²- 7xy)= -3x³ + 2x²y + 5x³ - 35x²y= = 2x³ - 33x²y
