Multiply (3x-5) (-x+4) and use distributive property and simply

Answer: - 3x² + 17x - 20

Step-by-step explanation:

Hi, to solve this we have to apply distributive property.

To do this, we have to multiply each addend separately and then add the products.

(3x-5) (-x+4)

(3x.-x) (3x. 4) (-5.-x) (-5.4)

-3x² + 12 x+5x-20

Adding alike terms to simplify (in this case 12x + 5x)

-3x² + 17x - 20

Feel free to ask for more if needed or if you did not understand something.

(3x-5) (-x+4)

(3x) (-x) (3x) (4) (-5) (-x) (-5) (4)

-3x^ 2+12x+5x-20

-3x^2+17x-20

Answer: - 3x^2+17x-20
