Answer:
Option no.D ( 7 is the answer)
Step-by-step explanation:
4x³ + 8x² - x - 2 = 0
=> 4x²(x - 2) + 1(x - 2) = 0
=> (4x² + 1) (x -2) = 0
So, either (4x² + 1) or (x -2) will equal to 0. The value of x cannot be -ve so we consider here (x -2) = 0 => x = 2.
Now,
Putting the value of x = 2,
(2x + 3) = (2 × 2 + 3) = (4 + 3) = 7
