Question

Solve for x
3a2x2+8abx+4b2=0

Answer 1

Answer:

-2b/3a or -2b/a

Step-by-step explanation:

Using quadratic formula,

x = -b ±√b²-4ac/2a

x = -8ab ± √64a²b²- 48a²b² / 6a²

  = -8ab ±√16a²b²/6a²

  = -8ab ± 4ab/ 6a2

-8ab + 4ab / 6a2                  or -8ab -4ab / 6a²

= -4ab/ 6a²                                 = -12ab/6a²

= -2b/3a                                      = -2b / a
