C= (-2x+8)X5
C = - 10x - 40
I=2(3c-5)-(4c+3)x6
I = 6x - 10 - (24x + 18)
I = 6x - 10 - 24x - 18
I = - 18x - 28
K=(2x--5)(-5x+3)
K = - 10x² + 6x + 25x - 15
K = - 10x² + 31x - 15
M=(5x+4)(1x-9)
M = 5x² - 45x + 4x - 36
M = 5x² - 41x - 36
O=2(3x+4)(x-6)
O= 6 (3x² - 18x + 4x - 24)
O = 18x² - 108 + 24x - 144
O = 18x² + 24x - 252
Q=(2x+1)(3x-1)
Q = 6x² - 2x + 3x - 1
Q = 6x² + x - 1
L=5x+2)*2
L = 10x + 4
J=(5x+2)(6x-4)
J = 30x² - 20x + 12x - 8
J = 30x² - 8x - 8
