N^2+n/2=465

Question

N^2+n/2=465

Answer 1

We have a quadratic equation of the form  n^2+n/2-465=0. the solution of the quadratic is x=(-b±√(b^2-4*a*c))/2*a. the values will be a= 1; b= 1/2; c= -465. plugging this values we reach:

n= (-1/2±43.13)/2.

solve for n1 with plus sign and for n2 with the minus sign.

 

 

Answer 2

N^2 + n/2 + 465

 

2N^2 + N - 930= 0

 

 N = -1/4 ±√(1+7440)/4

 

      = -1/4 ±86.26/4 = 

 

       = - 21. 82, 21.31
