Final answer:

The polynomials subtraction 7x2-(-x2-10) simplifies to 8x2 + 10 by re-writing the negative elements as positive and combining like terms.

Step-by-step explanation:

To subtract the polynomials, 7x2-(-x2-10), you first rewrite the doubly negative elements as positive. Thus, the equation becomes 7x2 + x2 + 10. Then, combine like terms.

To combine like terms, simply add or subtract the coefficients of the like powers. In this case, we combine 7x2 and x2. 1 is the coefficient of x2, so, adding 7x2 and x2 results in 8x2. So, the final simplified form of the polynomials after subtraction is 8x2 + 10.
