Answer 1

x² + ax² - y - ay + cx² - cy = (x² + ax² + cx²) - (y + ay + cy) =
= x²(1 + a + c)- y(1 + a + c) = (1 + a + c)(x² - y)

x²y + x + xy² + y + 2xy + 2 = (x²y + xy² + 2xy) + (x + y + 2) =
= xy(x + y + 2) + (x + y + 2) = (x + y + 2)(xy + 1)

x² - 10x + 24 = (x - 4)(x - 6)

x² + 8x + 7 = ( x + 7)(x + 1)

Answer 2

N5
a)(x²+ax²+cx²)-(y+cy+ay)= x²(1+a+c)-y(1+a+c)=(1+a+c)(x²-y)

b)(x²y+xy²+2xy)+(x+y+2)=xy(x+y+2)+(x+y+2)=(x+y+2)(xy+1)

N6
a)(x-6)(x-4)

b)(x+7)(x+1)
