No idea what this is, sorry
Answer: x² - 4
<u>Four less than</u> the <u>square of a number</u>
↓ ↓
(Take away 4) x²
Four less than the square of a number = x² - 4
First expand it
Next subtract 14 - 2x + 4x so it can be 14 + 2x
Next subtract 14 from both sides
Next subtract 20 - 14 so it can be 6
Then divide both sides by 2
And lastly reduce the fraction 6/2 and once u reduce it u have your answer which is x = 3.

Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
(-5x + 6x²) - (6x² - 5x)
<u>Step 2: Simplify</u>
- [Distributive Property] Distribute negative: -5x + 6x² - 6x² + 5x
- [Subtraction] Combine like terms (x²): -5x + 5x
- [Addition] Combine like terms (x): 0
