Question #900fd

Answer 1

Solution: `n=12 or n= -6 1/3`

Explanation:

Comparing with standard equation `ax^2+bx+c =0`, here `a=3 ; b= -17 ; c = -228`

Quadratic formula is `x= (-b +- sqrt(b^2-4ac))/(2a) :. n = ( -(-17) +- sqrt((-17)^2-4*3*(-228)))/(2*3)=(17+- sqrt3025)/6 :. n= (17+-55)/6 :. n=72/6=12 or n =-38/6= -19/3 = -6 1/3`

Solution : `n=12 or n= -6 1/3`[Ans]
