Respuesta :
1. Distribute the -2x with the (x+3)
2.Multiply (x+1) and (x-2) which is (x2- x -2)
So far it should look like (-2x^2 -6x) - (x^2-x-2)
3. Distribute out the negative
Should look like this -2x^2 -6x - x^2+x+2
4. Lastly combine like terms
Your result should be:
-3x^2 - 5x + 2
Hope this helps!

-2x(x + 3) - (x + 1)(x - 2)
//Distribute
= (-2x² - 6x) - (x² - 2x + x - 2)
// Combine like terms
= (-2x² - 6x) - (x² - x - 2)
// Open brackets
= -2x² - 6x - x² + x + 2
//Combine like terms
= - 3x² - 5x + 2
//Factorise
= (1 - 3x)(x + 2)Answer: (1 - 3x)(x + 2)
