Step-by-step explanation:
Simplifying
(n + -1)(2n + -2) = 0
Reorder the terms:
(-1 + n)(2n + -2) = 0
Reorder the terms:
(-1 + n)(-2 + 2n) = 0
Multiply (-1 + n) * (-2 + 2n)
(-1(-2 + 2n) + n(-2 + 2n)) = 0
((-2 * -1 + 2n * -1) + n(-2 + 2n)) = 0
((2 + -2n) + n(-2 + 2n)) = 0
(2 + -2n + (-2 * n + 2n * n)) = 0
(2 + -2n + (-2n + 2n2)) = 0
Combine like terms: -2n + -2n = -4n
(2 + -4n + 2n2) = 0
Solving
2 + -4n + 2n2 = 0
Solving for variable 'n'.
Factor out the Greatest Common Factor (GCF), '2'.
2(1 + -2n + n2) = 0
Factor a trinomial.
2((1 + -1n)(1 + -1n)) = 0
Ignore the factor 2.
Subproblem 1
Set the factor '(1 + -1n)' equal to zero and attempt to solve:
Simplifying
1 + -1n = 0
Solving
1 + -1n = 0
Move all terms containing n to the left, all other terms to the right.
Add '-1' to each side of the equation.
1 + -1 + -1n = 0 + -1
Combine like terms: 1 + -1 = 0
0 + -1n = 0 + -1
-1n = 0 + -1
Combine like terms: 0 + -1 = -1
-1n = -1
Divide each side by '-1'.
n = 1
Simplifying
n = 1
Subproblem 2
Set the factor '(1 + -1n)' equal to zero and attempt to solve:
Simplifying
1 + -1n = 0
Solving
1 + -1n = 0
Move all terms containing n to the left, all other terms to the right.
Add '-1' to each side of the equation.
1 + -1 + -1n = 0 + -1
Combine like terms: 1 + -1 = 0
0 + -1n = 0 + -1
-1n = 0 + -1
Combine like terms: 0 + -1 = -1
-1n = -1
Divide each side by '-1'.
n = 1
Simplifying
n = 1
Solution
n = {1, 1}
