How to Factor x squared plus 4x plus 4?

Answer 1

The same way you'd factor any other similar equation. You're going to run into the complication that the roots of that equation are not real numbers, though; unless you know what complex numbers are, you won't be able to do it.

Answer 2

Yes. There is an easy solution for the difference of two squares, but the sum of two squares is a different matter.

Answer 3

x2 + 4x + 4 = (x+2)2

Answer 4

(x + 2)(x + 2)

Answer 5

That factors to 4(x^2 + 4)

Answer 6

4x + 16 = 4 (x + 4)

Answer 7

4(x + 4)
