the first step to solving this expression is to multiply each term in the parenthesis by 2x 2x × x² + 2x × x - 2x × 5 now you need to calculate the first product 2x³ + 2x × x - 2x × 5 now youll calculate the second product of the expression 2x³ + 2x² - 2x × 5 lastly,, calculate the final product in the expression 2x³ + 2x² - 10x since you cant simplify this expression any further,, the answer to your question is 2x³ + 2x² - 10x let me know if you have any further questions :)
