3x(4x-3y)-2(4x-3y)

distributive property

(3x-2)(4x-3y) if you find that easier

LOL, more MITx ?

absolutely not, more MITX would be more like

In an effort to purify the output from a catalytic chemical reaction, C-Cl bonds are to be broken in a gaseous compound by means of LASER radiation. Determine the longest wavelength of radiation still capable of breaking the C-Cl bond. Express your answer in meters.

[Given: BEC-C = 334 kJ/mol; BECl-Cl = 243 kJ/mol]

To simplify the expression 3x(4x - 3y) - 2(4x - 3y), you can use the distributive property of multiplication over addition/subtraction.

First, let's apply the distributive property to the number 3x and simplify the expression inside the parentheses:
3x * 4x - 3x * 3y = 12x^2 - 9xy

Next, let's apply the distributive property to the number -2 and simplify the expression inside the parentheses:
-2 * 4x + 2 * 3y = -8x + 6y

Now, we can combine the two simplified expressions:
12x^2 - 9xy - 8x + 6y

And that is the simplified form of the expression 3x(4x - 3y) - 2(4x - 3y).
