Question

How to factor x^2+8x+12

Answer 1

 x^2+8x+12 = (x + 6)(x + 2)

Answer 2

x^2+8x+12
(x   )(x  )   We know x has to appear twice
Then we say what two numbers multiplied together gets you 12 and when added together gets you 8
We know thats 2 and 6
(x 2)(x 6)
And since they are both positive...
(x+2)(x+6)
