Solution for (n+7)(n-2)-n(n+5)=66 equation:


Simplifying
(n + 7)(n + -2) + -1n(n + 5) = 66

Reorder the terms:
(7 + n)(n + -2) + -1n(n + 5) = 66

Reorder the terms:
(7 + n)(-2 + n) + -1n(n + 5) = 66

Multiply (7 + n) * (-2 + n)
(7(-2 + n) + n(-2 + n)) + -1n(n + 5) = 66
((-2 * 7 + n * 7) + n(-2 + n)) + -1n(n + 5) = 66
((-14 + 7n) + n(-2 + n)) + -1n(n + 5) = 66
(-14 + 7n + (-2 * n + n * n)) + -1n(n + 5) = 66
(-14 + 7n + (-2n + n2)) + -1n(n + 5) = 66

Combine like terms: 7n + -2n = 5n
(-14 + 5n + n2) + -1n(n + 5) = 66

Reorder the terms:
-14 + 5n + n2 + -1n(5 + n) = 66
-14 + 5n + n2 + (5 * -1n + n * -1n) = 66
-14 + 5n + n2 + (-5n + -1n2) = 66

Reorder the terms:
-14 + 5n + -5n + n2 + -1n2 = 66

Combine like terms: 5n + -5n = 0
-14 + 0 + n2 + -1n2 = 66
-14 + n2 + -1n2 = 66

Combine like terms: n2 + -1n2 = 0
-14 + 0 = 66
-14 = 66

Solving
-14 = 66
