Answer:

(6m² + 12m + 2) / (6m + 1)

Explanation:

multiply both sides by m.

we get m² - 1 = 6m

move the -1 to the other side, so it becomes +1

m² = 6m + 1

so m² + 1/m² = (6m + 1) + 1/(6m + 1)

get a common denominator by squaring (6m + 1)

(6m + 1)².

we now have (6m + 1)² / (6m + 1) + 1/(6m + 1).

we now add the numerators.

(6m + 1)² + 1 = (6m² + 6m + 6m + 1) + 1 = 6m² + 12m + 2.

numerator over denominator = (6m² + 12m + 2) / (6m + 1)
