Heya! I am going to show you something step by step, I hope this helps you hun.

=(x+−4)(x+5)

=(x)(x)+(x)(5)+(−4)(x)+(−4)(5)

=x2+5x−4x−20

=x2+x−20

(The 2 is to the second power between.)

Step-by-step explanation:

Step 1: Define

(3x² + 2y² - 3x) + (2x² + y² - 2x) - (x² + 3y² + x)

Step 2: Simplify

[Distributive Property] Distribute negative: 3x² + 2y² - 3x + 2x² + y² - 2x - x² - 3y² - x
Combine like terms (x²): 4x² + 2y² - 3x + y² - 2x - 3y² - x
Combine like terms (y²): 4x² - 3x - 2x - x
Combine like terms (x): 4x² - 6x
