Solution for 0=n^2+70n equation:


Simplifying
0 = n2 + 70n

Reorder the terms:
0 = 70n + n2

Solving
0 = 70n + n2

Solving for variable 'n'.
Remove the zero:
-70n + -1n2 = 70n + n2 + -70n + -1n2

Reorder the terms:
-70n + -1n2 = 70n + -70n + n2 + -1n2

Combine like terms: 70n + -70n = 0
-70n + -1n2 = 0 + n2 + -1n2
-70n + -1n2 = n2 + -1n2

Combine like terms: n2 + -1n2 = 0
-70n + -1n2 = 0

Factor out the Greatest Common Factor (GCF), '-1n'.
-1n(70 + 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 '(70 + n)' equal to zero and attempt to solve: Simplifying 70 + n = 0 Solving 70 + n = 0 Move all terms containing n to the left, all other terms to the right. Add '-70' to each side of the equation. 70 + -70 + n = 0 + -70 Combine like terms: 70 + -70 = 0 0 + n = 0 + -70 n = 0 + -70 Combine like terms: 0 + -70 = -70 n = -70 Simplifying n = -70

Solution

n = {0, -70}
