Best ResponseYou've already chosen the best response.0Because they all have the same square roots, they are like terms, so you can subtract them all together.

Best ResponseYou've already chosen the best response.1Let's say a positive number of dollars is money you have, and a negative number of dollars is money you owe. What is $5  12$  $2 = ?

Best ResponseYou've already chosen the best response.0Yep, and then the square root stays the same because they are like terms.

Best ResponseYou've already chosen the best response.1Correct. You'd have $9 It's the same with x and with \(\sqrt{11} \) Since you are combining a number of the same things, in this case all terms have \(\sqrt {11} \), just combine the coefficients and then write \(\sqrt{11} \) at the end. $5  $12  $2 = $9 5x  12x  2x = 9x Similarly: \(5\sqrt{11}  12\sqrt{11}  2\sqrt{11} = 9\sqrt {11}\)
