Final answer:
To find the expression that equals 3C + 2B in standard form, substitute the values of C and B into the expression and simplify.
Step-by-step explanation:
To find the expression that equals 3C + 2B in standard form, we substitute the values of C and B into the expression and simplify:
3C + 2B = 3(n² - 2) + 2(3n + 8n² + 2)
Expanding this expression, we get:
3C + 2B = 3n² - 6 + 6n + 16n² + 4
Combining like terms, we have:
3C + 2B = 19n² + 6n - 2
This is the expression that equals 3C + 2B in standard form.
