Square brackets are used to group together numbers, variables or terms that already include parantheses. ex. 5[1+2+(x+2)^2 +4(a^2+b^2)]=0. First, take care of items in parantheses.5[1+2+x^2+2x+4+4a^2+4b^2]=0. Next, distribute the 5 to each item in brackets.5+10+5x^2+10x+20+20a^2+20b^2=0. Now, you can add like terms. Hope this helps!!
