Consider the expression 5x^2 - 3x + 8 - 2x^2 + 7x - 5. A student groups the constant terms (the plain numbers) as like terms. What is the value of the combined constant term?

Question

Accepted Answer

3. Constants are like terms: 8 - 5 = 3. (x^2-terms give 3x^2, x-terms give 4x.) Combined constant is 3.

Consider the expression $5 x^{2} - 3 x + 8 - 2 x^{2} + 7 x - 5$ .
A student groups the constant terms (the plain numbers) as like terms.
What is the value of the combined constant term?
