কোন দুটি x2-x-6=0 সমীকরণের মূল ?
- 2,3
- 2,-3
- -2,3
- -2,-3
Answer: -2,3
Explanation: x2 – x – 6 = 0
Or, x^2 – 3x + 2x – 6 = 0
Or, x(x – 3) + 2(x – 3) = 0
Or, (x – 3)(x + 2) = 0
So, x = 3 or, – 2
কোন দুটি x2-x-6=0 সমীকরণের মূল ?
Answer: -2,3
Explanation: x2 – x – 6 = 0
Or, x^2 – 3x + 2x – 6 = 0
Or, x(x – 3) + 2(x – 3) = 0
Or, (x – 3)(x + 2) = 0
So, x = 3 or, – 2
