PEMDAS and also probaly this wld be the signs :FIRST PIRENTHISES: square rooot of 3 and 2 then multiply that. then subtract the square roots of 2 and 6 multiplied. 2ND PERENTHISES: square route of 5 and 2 multiplied, then add that to the square routes of 3 and 6 multiplied.
again, i am probaly not right. but this is how i wld do it. btw i payed no attention to the answer. but thts how i wld do it. hope i helped!

Verified answer
(3√2 - 2√6)(5√2 + 3√6)
-->multiply through
3√2*5√2 + -2√6*5√2 + 3√2*3√6 + -2√6*3√6
-->remember that when you multiply √6*√6 = √36 = 6, so this turns into:
3*5*√4 + -2*5*√12 + 3*3*√12 + -2*3*√36
15*2 + -10*√4*√3 + 9*√4*√3 + -6*6
30 + 10*2*√3 + 9*2*√3 + -36
30 + 20√3 + 18√3 + -36
38√3 + -6
