Lesson Steps
Step | Type | Explanation | Answer |
---|---|---|---|
1 |
Problem |
Simplify the following expression: |
|
2 |
Step |
Identify the Expression: |
\$(2\sqrt(3) + \sqrt(12)) \times (\sqrt(3) - \sqrt(6))\$ |
3 |
Step |
Simplify \$\sqrt(12)\$ |
\$\sqrt(12) = \sqrt(4 \times 3) = 2\sqrt(3)\$ \$ (2\sqrt(3) + 2\sqrt(3)) \times (\sqrt(3) - \sqrt(6))\$ |
4 |
Step |
Combine Like Terms: |
\$(2\sqrt(3)) + (2\sqrt(3)) = 4\sqrt(3)\$ \$4\sqrt(3) \times (\sqrt(3) - \sqrt(6))\$ |
5 |
Step |
Distribute \$4\sqrt(3)\$ |
\$4\sqrt(3) \times \sqrt(3) - 4\sqrt(3) \times \sqrt(6)\$ |
6 |
Step |
Simplify Each Term: |
\$4\sqrt(3) \times \sqrt(3) = 4 \times 3 = 12\$ \$4\sqrt(3) \times \sqrt(6) = 4 \times \sqrt(18) = 4 \times 3\sqrt(2) = 12\sqrt(2)\$ |
7 |
Step |
Combine the Simplified Terms: |
\$12 - 12\sqrt(2)\$ |
8 |
Step |
Therefore, the simplified expression is \$12 - 12\sqrt(2)\$. |
|
9 |
Choice.A |
This option is Incorrect, as it doesn’t match our result, which includes a subtraction term |
\$12\sqrt(2)\$ |
10 |
Choice.B |
This option is Incorrect, as it only represents part of the final result and misses the constant termt |
\$- 12\sqrt(2)\$ |
11 |
Choice.C |
This option is Correct, as it exactly matches the simplified expression |
\$12 - 12\sqrt(2)\$ |
12 |
Choice.D |
This option is Incorrect, as our simplification does not yield any term with \$12\sqrt(3)\$ |
\$12\sqrt(3)\$ |
13 |
Answer |
Option |
C |
14 |
Sumup |
Can you summarize what you’ve understood in the above steps? |
