Answer: To solve this expression, we need to simplify it using the order of operations (PEMDAS) and perform the indicated operations:
2.3x^2 + 69 / 465
First, we need to simplify the fraction 69/465. Both the numerator and denominator have a common factor of 3, so we can simplify the fraction by dividing both by 3:
69 / 465 = 23 / 155
Now we can substitute this simplified fraction back into the original expression:
2.3x^2 + 23 / 155
The expression is now in simplified form, and there are no more operations we can perform. So this is the final answer.
Alternatively, if the expression was meant to be solved for x, we would need an equation (e.g., 2.3x^2 + 69 / 465 = some value) in order to solve for x. As it stands, we cannot solve for x with the given expression.
