Certainly! Let's evaluate the expression [tex]\(3x^2 - y\)[/tex] step by step.
1. Identify the Expression: The expression we need to evaluate is [tex]\(3x^2 - y\)[/tex].
2. Substitute the Values (If Given): Let me take you through how we'd proceed assuming we have specific values for [tex]\(x\)[/tex] and [tex]\(y\)[/tex].
Without knowing specific values for [tex]\(x\)[/tex] and [tex]\(y\)[/tex], we can only simplify the expression, not evaluate it to a single numeric value. However, let's assume we have some hypothetical values:
Suppose [tex]\(x = 2\)[/tex] and [tex]\(y = 5\)[/tex].
3. Calculate [tex]\(x^2\)[/tex]: First, find the square of [tex]\(x\)[/tex]:
[tex]\[
x^2 = 2^2 = 4
\][/tex]
4. Multiply by 3: Next, multiply this result by 3:
[tex]\[
3x^2 = 3 \times 4 = 12
\][/tex]
5. Subtract [tex]\(y\)[/tex]: Finally, subtract [tex]\(y\)[/tex] from the result:
[tex]\[
3x^2 - y = 12 - 5 = 7
\][/tex]
So, if [tex]\(x = 2\)[/tex] and [tex]\(y = 5\)[/tex], the result of the expression [tex]\(3x^2 - y\)[/tex] is [tex]\(7\)[/tex].
If [tex]\(x\)[/tex] and [tex]\(y\)[/tex] are not specified, the result will remain in the form of [tex]\(3x^2 - y\)[/tex].
I hope this step-by-step explanation helps! Let me know if you have any more questions or need further clarification.
