4x^2 – 23x + 33 কে উৎপাদকে বিশ্লেষন করুন ।

A    (4x-11)(x-3)

B    (x-11)(4x-3)

C    (4x+3)(x-11)

D    (4x-11)(x+3)

Solution

Correct Answer: Option A

 

এখানে, 4 ×33 =132

এখানে, (-11)×(-12) =132 এবং (-11)+(-12)= -23

4x^2 – 23x + 33 = 4x^2 –11x -12x + 33

                             =x (4x-11) – 3 (4x-11)

                 =(4x-11)(x-3)
