multiplying each combination of the brackets so:

root5 *root 5 = root 25

-root 6* root 5 = -root 30

-root 6* root 2 = -root 12

root5 *root 2 = root 10

= root25 – root30 – root12 +root10

=5 – root30 – root12 +root10

Use the acronym FOIL

Multiply the First Ones,

Then the outside ones,

Then the inside ones.

Then the last ones

I think the answer ends up being -0.78 but not too sure.

(root5-root6)*(root5+root2)

=[(root5*root5)+(root5*root2)]-[(root6*root5)+(root6*root2)]

=(root25+root10)-(root30+root12)

=5 + root10 – root30 -root12
