x^2 + 3
= x^2 - (-3)
= x^2 - (√-3)^2
= x^2 - (i√3)^2
= [x - (√3)i][x + (√3)i]
x2 + 4x + 3 =(x + 3) (x + 1)
3(x + 4)(x + 1)
2(x^2 + 2)(x + 3)
x2 + x - 12 = (x + 4) (x - 3)
x^2 + 3 = x^2 - (-3) = x^2 - 3i^2 = (x - i√3)(x + i√3)
(x + 3)(x + 3)
(x + 3)(x + 2)
(x + 3)(x - 2)
(x + 2)(x + 3)
Asuming it starts "x squared" the the answer is (x-3)(x-3) or (x - 3)squared
(x - 7)(x - 3)
(x + 15)(x - 3)
x2 + 4x + 3 =(x + 3) (x + 1)
(3x + 3y)(x + y) = 3(x + y)2
(x + 3)(x + 2)
2(x + 3)(x + 1)
3(x + 4)(x + 1)
