Factor 2x + 4

• x (2 + x)

  Or maybe this is the answer

• 2(2x + 1)

  It's this answer

• 4(x +2)

  Um- Hello!

• 2(x +2)

  This clearly is NOT the answer

Find the LCM f the expressions: 2x+4 and x²-x-6

if you have 2(x+2) and (x+2) (x-3)

• (x-1)(x-1)(x-2)

• (x-1)(x-2)

• (x-1)(x-2)(x-2)

• (x-1)(x-3)

• x can't = 1 or 2

• x can't = -1 or 2

• x can't = -1 or -2

• x can't = 1 or -2
