2. Descompuneți în factori:

a) 6x+5xy; b) ax+bx-cx; c) x la a 2-6x;

3.

a) 4(x-2)+y(x+2); b) -3a(x+3)+6b(x+3);

c) (x-2)•x+4(x-2);

Urgent!!

Answer 1

1)

a) 3x + 3y = 3(x + y)

b) 3x - 3y + 3z = 3(x - y + z)

c) 3xy + 3ab + 3 = 3(xy + ab + 1)

2)

a) 6x + 5xy = x(5y + 6)

b) ax + bx - cx = x(a + b - c)

c) x² - 6x = x(x - 6)

3)

a) 4(x - 2) + y(x + 2) = 4x - 8 + xy + 2y

b) -3a(x + 3) + 6b(x + 3) = (x + 3)(6b - 3a)

c) (x - 2)•x + 4(x - 2) = (x - 2)(x + 4)

Answer 2

1.a)3(x+y)

b)3(x-y+z)

c)3(cu+ab+1)

2.a)x(6+5y)

b)x(a+b-c)

c)x la a 2-6x=x(x 2-6)

3.a)(4+y)(x-2)(x+2)

b)(x+3)(-3a+6b)

c)(x-2)(x+4)
