Question

simplify $-2\sqrt{3} - 2\sqrt{3} + 2\sqrt{3}$
solution
$-2\sqrt{3}$
decimal
$-3.46410...$
solution steps
$-2\sqrt{3} - 2\sqrt{3} + 2\sqrt{3}$
add similar elements: $-2\sqrt{3} + 2\sqrt{3} = 0$
$= -2\sqrt{3}$

Explanation:

Step1: Group like radical terms

$-2\sqrt{3} + (-2\sqrt{3}) + 2\sqrt{3}$

Step2: Combine matching radicals first

$-2\sqrt{3} + 2\sqrt{3} = 0$

Step3: Simplify the remaining term

$0 - 2\sqrt{3} = -2\sqrt{3}$

Answer:

$-2\sqrt{3}$ (or approximately $-3.46410...$ in decimal form)
