10n squared -26n +12

Sagot :

10n^2-26n+12
their gcf is 2
2(5n^2-13n+6)
2(5n-3)(n-2)
n=3/5 or n=2

Answer:

Simplifying

2n + 4 + 5n = -3n + 2

Reorder the terms:

4 + 2n + 5n = -3n + 2

Combine like terms: 2n + 5n = 7n

4 + 7n = -3n + 2

Reorder the terms:

4 + 7n = 2 + -3n

Solving

4 + 7n = 2 + -3n

Solving for variable 'n'.

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

Add '3n' to each side of the equation.

4 + 7n + 3n = 2 + -3n + 3n

Combine like terms: 7n + 3n = 10n

4 + 10n = 2 + -3n + 3n

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

4 + 10n = 2 + 0

4 + 10n = 2

Add '-4' to each side of the equation.

4 + -4 + 10n = 2 + -4

Combine like terms: 4 + -4 = 0

0 + 10n = 2 + -4

10n = 2 + -4

Combine like terms: 2 + -4 = -2

10n = -2

Divide each side by '10'.

n = -0.2

Simplifying

n = -0.2
