Multiply: (3x - 5)(-x + 4)
insens350 [35]

Answer:

-3x²+17x-20

Step-by-step explanation:

When you apply the distributive property (which you did correctly), you simply multiply each number or variable in which you have to distribute it to (which again you wrote correctly) and then you add them all together.

(3x)(-x)=-3x²

+

(3x)(4)=12x

+

(-5)(-x)=5x

+

(-5)(4)=-20

Add those and you will get your answer. Hope this helped :)
