Question

Solve the ques simplify the following:(root7-root6)(3root7-2root6
​

Answer 1

Answer:

$(\sqrt{7}-\sqrt{6})(3\sqrt{7} -2\sqrt{6})\\(3\sqrt{7}*\sqrt{7}-3\sqrt{6}*\sqrt{7})-(-2\sqrt{6}*\sqrt{7}+((-2\sqrt{6})*(-\sqrt{6}))\\(21-3\sqrt{42}})-(-2\sqrt{42}+12)\\21-3\sqrt{42}+2\sqrt{42}-12\\ 9-\sqrt{42}$
