Final answer:
To express the polynomial 7x³ - 10x³ + x in standard form, we need to combine like terms. Like terms have the same variable raised to the same power. In this case, the like terms are the x³ terms. We can combine them by adding their coefficients. So, -3x³ + x is the standard form of the given polynomial.
