(3x + 2)(2x - 6) = (4 - 3x)(1 - 2x) - 10 হলে, x এর মান কত?
Solution
Correct Answer: Option B
(3x + 2)(2x - 6) = (4 - 3x)(1 - 2x) - 10
or, 6x2 - 18x + 4x - 12 = 6x2 - 3x - 8x + 4 - 10
or, - 14x - 12 = - 11x - 6
or, - 3x = - 6 + 12 = 6
or, x = - 2
or, 6x2 - 18x + 4x - 12 = 6x2 - 3x - 8x + 4 - 10
or, - 14x - 12 = - 11x - 6
or, - 3x = - 6 + 12 = 6
or, x = - 2
