slove

We cannot solve the expression as it is not an equation. However, we can evaluate the expression using the given values.

|4x^2-9y|

Since we are not given any specific values for x or y, we cannot simplify the expression further.

To evaluate the expression |4x^2 - 9y|, you need the values of x and y. Once you have those values, you can substitute them into the expression and calculate the result. Please provide the values of x and y so that I can help you solve the expression.

To evaluate the expression |4x^2 - 9y|, we need values for x and y. It seems that there are no specific values given for x and y in your question. In order to find the value of the expression, we need to substitute numerical values for both x and y.

Once you have numerical values for x and y, you can perform the necessary calculations.

Here's an example of how you can evaluate the expression:

Let's say x = 2 and y = 3.

Substituting these values into the expression, we get:

|4(2)^2 - 9(3)|

Simplifying further:

|4(4) - 9(3)|

|16 - 27|

Now we need to take the absolute value of the result:

| -11 |

Since -11 is negative, the absolute value of -11 is simply 11.

Therefore, when x = 2 and y = 3, the value of the expression |4x^2 - 9y| is 11.

Remember, to evaluate the expression, you need specific values for x and y, and then you can substitute those values and perform the calculations accordingly.
