Answer 2

$\large \bf \it{Hey \: User!!!}$

given the equations are -5a² + 8ab, -3a² and 14a² - 11ab

we have to find the coefficient of a² of the sum of these equations.

sum of -5a² + 8ab, -3a² and 14a² - 11ab = ( -5a² + 8ab ) + ( -3a² ) + ( 14a² - 11ab )
= -5a² + 8ab - 3a² + 14a² - 11ab
= -5a² - 3a² + 14a² + 8ab - 11ab
= -8a² + 14a² - 3ab
= 6a² - 3ab

here, coefficient of a² is 6.

hence right option is d) 6
