Final answer:
The expression (10m – 6) – (7m – 4) can be simplified to 3m – 2.
Step-by-step explanation:
The expression that can be used to find the difference of the polynomials (10m – 6) – (7m – 4) is:
(10m – 6) – (7m – 4) = 10m – 6 – 7m + 4 = (10m – 7m) – 6 + 4 = 3m – 2
When subtracting polynomials, you distribute the subtraction sign to all terms inside the parentheses. Then, combine like terms to simplify the expression.
