Answer 5

First thing to note is that the term under the radical signs are both 9x. This means that we can easily subtract \(2\sqrt{9x} - 7\sqrt{9x}\) by just doing \((2-7)\sqrt{9x}\).

So what do you get?

Answer 6

\[-5\sqrt{9x}\]

Answer 7

Correct. Now look at the terms under the radical sign: 9 and x. Which one can you simplify more (in other words, take the square root of)?

Answer 8

so would it be \[-5\sqrt{x}\]

Answer 9

Nope. First answer the question: What term under the radical sign can you take the square root of?

Answer 10

9

Answer 11

which is 3

Answer 12

Good. So you need to take that 3 and bring it out to multiply it with the -5.

\(\large (-5 \times \color{red}{3})\sqrt{x}\)

So what's your final answer?

Answer 13

\[-15\sqrt{x}\]

Answer 14

Great!
