(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
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
