What is the factor of 9x2 minus 12x minus 4?

Answer 1

There's a chance this was notated incorrectly. It looks like it wants to be some combination of 3x and 2.

9x2 + 12x + 4 = (3x + 2)(3x + 2) or (3x + 2)2

-9x2 - 12x - 4 = -(3x + 2)2

9x2 - 12x + 4 = (3x - 2)2

-9x2 + 12x - 4 = -(3x - 2)2

Answer 2

If that's + 4, the answer is 4(x - 1)(x - 1)

Answer 3

If the missing signs are pluses, that's (2x + 3)(x + 3)

Answer 4

9x2 - 4 = (3x)2 - 22 = (3x - 2)(3x + 2)

Answer 5

9x2 - 4 = (3x)2 - 22 = (3x + 2)(3x - 2)

Answer 6

3x4(3x3 - 8)

Answer 7

8x2 + 6x - 9 = (2x + 3)*(4x - 3)
