How do you factor 3x squared minus 12?

Answer 1

3X2 - 12

3(X2 - 4)
=========All the factoring that can be done here.

Answer 2

-2x3 - 10x2 - 12x = -2x*(x2 + 5x + 6) = -2x*(x + 2)*(x + 3)

Answer 3

For a start, you can look for a common factor, and separate it. What remains (the other factor) will only be a polynomial of degree 2; I assume you already learned how to factor that.

Answer 4

x(x - 2)(7x + 2)

Answer 5

3(3x + 2)(3x - 2)

Answer 6

(2x + 1)(x - 4)

Answer 7

-2x(x + 3)(x + 2)

Answer 8

2x(x + 1)(x - 6)

Answer 9

3x^3(x - 4)
