a+b=14 anda*b = 49 The solution to this new system of equations is a=7, b=7. original expression is (n+7)(n+7), or (n+7)^2. *As always meaning when the coefficient of n^2 is 1. When the coefficient is 2+, it's not as simple but the same idea hope this helps

(n-7) (n-7) will be your answer

n x n = n²

n x -7 = -7n
n x - 7 = -7n
-7n +(-7n) = -14n
-7 x -7 = 49

(n-7)² is your answer

hope this helps

and if you are doing the other thing

n = 7, 7

hope this helps
