Solution for (n*n+5*5)-(n*n+3*3)=4(n+4) equation:


Simplifying
(n * n + 5 * 5) + -1(n * n + 3 * 3) = 4(n + 4)

Multiply n * n
(n2 + 5 * 5) + -1(n * n + 3 * 3) = 4(n + 4)

Multiply 5 * 5
(n2 + 25) + -1(n * n + 3 * 3) = 4(n + 4)

Reorder the terms:
(25 + n2) + -1(n * n + 3 * 3) = 4(n + 4)

Remove parenthesis around (25 + n2)
25 + n2 + -1(n * n + 3 * 3) = 4(n + 4)

Multiply n * n
25 + n2 + -1(n2 + 3 * 3) = 4(n + 4)

Multiply 3 * 3
25 + n2 + -1(n2 + 9) = 4(n + 4)

Reorder the terms:
25 + n2 + -1(9 + n2) = 4(n + 4)
25 + n2 + (9 * -1 + n2 * -1) = 4(n + 4)
25 + n2 + (-9 + -1n2) = 4(n + 4)

Reorder the terms:
25 + -9 + n2 + -1n2 = 4(n + 4)

Combine like terms: 25 + -9 = 16
16 + n2 + -1n2 = 4(n + 4)

Combine like terms: n2 + -1n2 = 0
16 + 0 = 4(n + 4)
16 = 4(n + 4)

Reorder the terms:
16 = 4(4 + n)
16 = (4 * 4 + n * 4)
16 = (16 + 4n)

Add '-16' to each side of the equation.
16 + -16 = 16 + -16 + 4n

Combine like terms: 16 + -16 = 0
0 = 16 + -16 + 4n

Combine like terms: 16 + -16 = 0
0 = 0 + 4n
0 = 4n

Solving
0 = 4n

Solving for variable 'n'.

Move all terms containing n to the left, all other terms to the right.

Add '-4n' to each side of the equation.
0 + -4n = 4n + -4n
Remove the zero:
-4n = 4n + -4n

Combine like terms: 4n + -4n = 0
-4n = 0

Divide each side by '-4'.
n = 0

Simplifying
n = 0
