Simplify 2 sqrrt2(-sqrrt8 + 2 sqrrt6)
I got 2squrrt2*-squrrt8*2squrrt2*2squrrt6 = -2sqrrt16+4squrrt12= 2squrrt4*squrrt4+4squrrt12 = -2(2)(2)=4squrrt12 = -8+4squrrt12 (answer B) but it was wrong?
Answer Options:

Simplify 2 sqrrt2(-sqrrt8 + 2 sqrrt6)
------------
2sqrt%282%29%2A%282sqrt%286%29+-+sqrt%288%29%29
= 4sqrt%2812%29+-+2sqrt%2816%29
= 8sqrt%283%29+-+8
========================
I got 2squrrt2*-squrrt8*2squrrt2*2squrrt6 = -2sqrrt16+4squrrt12= 2squrrt4*squrrt4+4squrrt12 = -2(2)(2)=4squrrt12 = -8+4squrrt12
= -8+%2B+8sqrt%283%29
It's not wrong, but you didn't simplify sqrt(12).
