answer is (3x+4)(4x+3)

if you want to check it, try to substitute any number to x like 1 on the equations..and try to find which equation would give the same answer.

12xÂ² + 25x + 12 = 0

12xÂ² + 16x + 9x + 12 = 0

Group factor

(12xÂ² + 16x) + (9x + 12) = 0

4x(3x + 4) + 3(3x + 4) = 0

(4x + 3)(3x + 4) = 0
