Answer» Here is your answer :- Let the present age of virat kohli be x years Virat kohli age 8 years age = x-8 Virat kohli age 6 years later = x + 6 (x-8)(x+6) = 680 x² + 6x -8x -48 = 680 x² -2x -48-680 = 0 x² -2x -728 = 0 x² - (28-26)x - 728 = 0 x² -28x + 26x -728 = 0 x ( x -28) + 26( x-28) = 0 (x-28) (x+26) = 0 x = 28

Answer»

Here is your answer :-

Let the present age of virat kohli be x years

Virat kohli age 8 years age = x-8

Virat kohli age 6 years later = x + 6

(x-8)(x+6) = 680

x² + 6x -8x -48 = 680

x² -2x -48-680 = 0

x² -2x -728 = 0

x² - (28-26)x - 728 = 0

x² -28x + 26x -728 = 0

x ( x -28) + 26( x-28) = 0

(x-28) (x+26) = 0

x = 28
