2x^2+4x+2 Carry the 2 over to the 3 behind the 4 and multiply so 2times2 is 4. So i new equation is. X^2+4x+4 Now you have to find the factors of 4 which is 1,4 and 2,2 So now you have to see which one adds up to 4 so 1+4 is 5 so cross that out and 2+2=4. So the two number is 2 and 2 now you have to bring down the x^2 and the signs. (X+2) (X+2) and thats your answer
