Respuesta :

-5x^4 (-3x^2 + 4x - 2) =

15x^6 - 20x^5 + 10x^4

Answer:

15x^6 − 20x^5 + 10x^4

Step-by-step explanation:

You distribute the -5x^4 across −3x^2+4x−2 then you add the exponents, remember that there is an "x" with no exponent counts as 1 so when you add the four from "-5x^4" just add one.
