You can factor out a 4 so you get: 4(4x^2 + 12x + 9) Then you have to multiply the x^2 term by the constant; 4 * 9 = 36. This 36 number is used to find out the middle terms, you have to find out what times what equals 36 but adds up to 12. 6 * 6 = 36, 6 + 6 = 12. So you get, 4(4x^2 + 6x + 6x + 9) Then you group; (4x^2 + 6x)(6x + 9) Then factor even more; 2x(2x + 3) 3(2x + 3) which is equivalent to (2x + 3)(2x + 3) But wait, don't forgot the 4 you factored out earlier; 4(2x + 3)(2x + 3) The answer is 4(2x + 3)(2x + 3).
