Question 544082
{{{2sqrt(18)-5sqrt(8)-2sqrt(12)}}} find the left over squares
{{{2sqrt(9*2)-5sqrt(4*2)-2sqrt(4*3)}}} (9,4,4 all squares) take square roots of them
{{{2(3)sqrt(2)-5(2)sqrt(2)-2(2)sqrt(3)}}} multiply roots to the number in front
{{{6sqrt(2)-10sqrt(2)-4sqrt(3)}}} the 6 and -10 have same variables
{{{(6sqrt(2)-10sqrt(2))-4sqrt(3)}}}add like terms
{{{(-4sqrt(2)-4sqrt(3))}}} take out the -4
{{{highlight(-4(sqrt(2)+sqrt(3)))}}} simplified
