Write the equivalent expression to (5x – 3x?) – (5x – 2) · (10x + 7x) in standard form
sveticcg [70]

Answer:

-35x³ - 39x² + 25x

Step-by-step explanation:

First write out the equation which is (5x - 3x²) - (5x - 2)(10x + 7x²). Then distribute 5x - 3x²  to -(50x² + 35x³ - 20x - 14x²). After that, combine the like terms and don't forget to distribute the negative as well, 5x - 3x² - 36x² - 35x³ + 20x. Lastly combine all the like terms to end up with this -35x³ - 39x² + 25x.

Hope this helps :)
