=(√6-√2/2)×(2√6+2√6/3)

=(√6-√2/2)×(8√6/3)

=(8×6)/3-(√2/2)×(8√6/3)

= 16-8√3/3

√8+√32+√ 18-√24

=2√2+4√2+3√2-2√6

=9√2-2√6

2x？ + 1=-(4x？ -2x-5)

2x？ + 1+4x？ -2x-5=0

6x？ -2x-4=0

3x？ -x-2=0

(x- 1)(3x+2)=0

So x= 1 or x=-2/3.

=4√+√2 1-4√3

=√2 1

(2√ 12-3√ one sixth) ×√6

=(4√3-√6/2)×√6

= 12√2-3
