Question 65701
Simplify by combining like terms:

(sqrt3 + 5)(sqrt3 - 3)

No, the 3's are not like terms:
{{{(sqrt(3)+5)(sqrt(3)-3)}}}
{{{sqrt(3)*(sqrt(3)-3)+5*(sqrt(3)-3)}}}
{{{sqrt(3*3)-3*sqrt(3)+5sqrt(3)-15}}}
{{{3+(-3+5)*sqrt(3)-15}}}
{{{3-15+2*sqrt(3)}}}
{{{highlight(-12+2*sqrt(3))}}}
Happy Calculating!!!
