Solution for -4(n)=n^2-n equation:


Simplifying
-4(n) = n2 + -1n

Reorder the terms:
-4n = -1n + n2

Solving
-4n = -1n + n2

Solving for variable 'n'.

Combine like terms: -4n + n = -3n
-3n + -1n2 = -1n + n2 + n + -1n2

Reorder the terms:
-3n + -1n2 = -1n + n + n2 + -1n2

Combine like terms: -1n + n = 0
-3n + -1n2 = 0 + n2 + -1n2
-3n + -1n2 = n2 + -1n2

Combine like terms: n2 + -1n2 = 0
-3n + -1n2 = 0

Factor out the Greatest Common Factor (GCF), '-1n'.
-1n(3 + n) = 0

Ignore the factor -1.

Subproblem 1

Set the factor 'n' equal to zero and attempt to solve: Simplifying n = 0 Solving n = 0 Move all terms containing n to the left, all other terms to the right. Simplifying n = 0

Subproblem 2

Set the factor '(3 + n)' equal to zero and attempt to solve: Simplifying 3 + n = 0 Solving 3 + n = 0 Move all terms containing n to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + n = 0 + -3 Combine like terms: 3 + -3 = 0 0 + n = 0 + -3 n = 0 + -3 Combine like terms: 0 + -3 = -3 n = -3 Simplifying n = -3

Solution

n = {0, -3}
