Final answer:
To solve the expression 2/3x - x-3/10x², find the common denominator for the fractions and combine like terms within the numerator.
Step-by-step explanation:
To solve the expression 2/3x - x-3/10x², we can simplify the expression by finding a common denominator for the fractions. The common denominator is 10x². So, we multiply the first fraction by 10x and the second fraction by 3:
2/3x - x-3/10x² = (20x - 3x - 3) / 10x²
Combine like terms within the numerator:
(17x - 3) / 10x²
This is the simplified form of the expression.
