To evaluate the expression [tex]\(3x^2 - 7y\)[/tex], let's break it down step by step.
1. Identify the Terms:
The expression [tex]\(3x^2 - 7y\)[/tex] consists of two terms:
- [tex]\(3x^2\)[/tex]: This is a quadratic term in [tex]\(x\)[/tex], where 3 is the coefficient and [tex]\(x^2\)[/tex] indicates [tex]\(x\)[/tex] raised to the power of 2.
- [tex]\(-7y\)[/tex]: This is a linear term in [tex]\(y\)[/tex], where -7 is the coefficient of [tex]\(y\)[/tex].
2. Combine the Terms:
The expression is already simplified; it is the sum (or difference, in this case) of the two terms identified above.
Thus, the final expression, already simplified and combined, is:
[tex]\[3x^2 - 7y\][/tex]
This concludes the step-by-step breakdown of the given mathematical expression.
