Answer:
-3x²+17x-20
Step-by-step explanation:
First, multiply 3x by -x:
[tex]3x\times-x=-3x^{2}[/tex]
Next, multiply 3x by 4
[tex]3x\times4=12x[/tex]
Next, multiply -5 by -x
[tex]-5\times-x=5x[/tex]
Then, multiply -5 by 4
[tex]-5\times4=-20[/tex]
This gets you [tex]-3x^{2} +12x+5x-20[/tex].
Lastly, simplify the equation by mixing 12x+5x, to get your answer:
-3x²+17x-20
