Answer: -3x² +17x -20
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
