Answer:
Given, the quadratic equation is 4x² − √3x − 5 = 0 -------------------- (1)
We have to find the constant to be added and subtracted to solve the quadratic equation by the method of completing the square.
By using algebraic identity,
(a - b)² = a² - 2ab + b² --------------------- (2)
Comparing (1) and (2),
a² = 4
a = 2
-2ab = -√3
2(2)b = √3
b = √3/4
b² = (√3/4)² = 3/16
So, 4x² - √3x - 5 + 3/16 - 3/16 = 0
(2x - √3/4)² - 5 - 3/16 = 0
(2x - 3/16)² = 5 + 3/16
(2x - 3/16)² = (80 + 3)/16
(2x - 3/16)² = 83/16
Therefore, the constant to be added and subtracted is 3/16.
