(-2-sqrt3) (-2+sqrt3) simplfy
\((-2-\sqrt3)(-2+\sqrt3)\)
=\(-((\sqrt3+2)(\sqrt3-2))\)
=\(-((\sqrt3)^2-2^2)\)
=\(-(3-4)\)
Do the last bit yourself. It's easy, trust me
(-2-sqrt3) (-2+sqrt3)
What is your problem with this question?
Just expand it like this
\(-2(-2+\sqrt3)\;\;\ -\sqrt3(-2+\sqrt3)\)
Post your answer or just the next step if you want and I will tell you if it is correct. :)
