Pomuszcie mam na jutro .... :)

Answer 1

A) 3x - 6 + 4x - 8 = 7x - 14 = 7(x-2)
b) 8x + 32 - 5x - 20 = 3x + 12 = 3(x + 4)
c) 3x² - 21 + 8x² - 56 = 11x² - 77 = 11(x² - 7)
d) 7x - 21 - x + 3 = 6x - 18 = 6(x-3)
e) 4x + 20 + 20x + 100 = 24x + 120 = 24(x + 5)
f) -2 + 0,2x - x + 10 = -0,8x + 8 = -0,8(x - 10)
