(iii) Rohan’s mother is

$26$ years older than him. The product of their ages (in years)

$3$ years from now will be

$360$ . We would like to find Rohan’s present age.

Required quadratic equation

Answer variants:

$x^2+x+306=0$

$x^2+x-306=0$

$2x^2-2x-528=0$

$x^2+32x+273=0$

$2x^2+2x-528=0$

$2x^2+x-528=0$

$x^2+32x-273=0$
