The roots of the equation 3a2x2 - abx - 2b2 = 0 are
-
-
b , - 2b a 3a -
b , 2b a 3a -
- b , - 2b a 3a - None of these
-
Correct Option: A
According to question ,
The given quadratic equation is
3a2x2 - abx - 2b 2 = 0 ⇒ 3a 2 x 2 - 3abx + 2abx - 2b 2 = 0
⇒ 3ax ( ax - b ) + 2b ( ax - b ) = 0
⇒ ( ax - b ) ( 3ax + 2b ) = 0
⇒ ax = b or 3ax = - 2b
| ⇒ x = | or x = - | ||
Hence , option A will be required answer .
