I don't believe there's an answer to this question.

12 + 6root3 and 12 - 6root3, either use the formula to solve a quadratic, or complete the square

Where's the root symbol on a keyboard btw?

Whoops, misread, it's 6 + 3 root 2 and 6 - 3 root2

nescio

no, still incorrect cc1

the two numbers are 6 + √54 and 6 - √54
