From delta math:
Subtract -2x^2 + 3x - 9 from 8x^2 + 10x - 10

Step-by-step explanation:

Step 1: Build the expression in numerical form.

Step 2: Distribute the negative sign.

Step 3: Combine like terms.

Therefore, the answer is .

in mathematics, a function is a relationship between two variables such that the value of one of the variables, called the dependent variable, is determined by the value of the other variable, called the independent variable. there is a specific term we use to describe the set of independent variables of a function.
