Given m + 1 / M = 3, find the square of M + 1 / 2 of M Be more reliable. I hope you can write down the process~

Given m + 1 / M = 3, find the square of M + 1 / 2 of M Be more reliable. I hope you can write down the process~

M + 1 / M = 3
Square of both sides: square of M + 1 / 2 of M + 2 = 9
So m squared + m squared = 7
