What is the equivalent of -3 (x+2)+(x-3)x

(-3x-6) + (x²-3x)
The expression you posted just had it simplified

-3 (x+2) + (x-3)x

First, we have to simplify the equation.

-3x - 6 + x² - 3x

Add your like terms.

x² + (-3x - 3x) - 6

Simplify.

x² - 6x - 6  ← That is your simplified version of the original equation, which is also equivalent to the original equation.

Now, to find another equivalent equation, you would multiply your simplified version with (2).

2(x² - 6x - 6)

2x² - 12x - 12 and x² - 6x - 6 are BOTH equivalent to your original equation.
