You can put this solution on YOUR website!
Multiply and simplify:
:
A. √5(2√10 + √2x)
sqrt%285%29%2A%282sqrt%2810%29%2Bsqrt%282x%29%29%29 = %282sqrt%2850%29%2Bsqrt%2810x%29%29 = %282sqrt%2825%2A2%29%2Bsqrt%2810x%29%29 = %282%2A5sqrt%282%29%2Bsqrt%2810x%29%29 = %2810sqrt%282%29%2Bsqrt%2810x%29%29; about all you can do with this



B. %282+-+sqrt%286%29%29%281+%2B+sqrt%286%29%29
FOIL
%282+-+sqrt%286%29%29%281+%2B+sqrt%286%29%29
2+%2B+2sqrt%286%29+-+sqrt%286%29+-+6 = -4+%2B+sqrt%286%29
