Tính 2y^2-1/16x^2

The expression 2y^2 - 1/16x^2 can be simplified further by factoring out a common factor from both terms.

First, let's factor out 2 from the first term:
2y^2 = 2 * y * y = 2y * y

Next, let's factor out 1/16 from the second term:
1/16x^2 = (1/16) * x * x = (1/16)x * x

Now, the expression becomes:
2y * y - (1/16)x * x

This can be further simplified as:
2y^2 - (1/16)x^2
