The expression 3x^2 - x^2 simplifies to 2x^2. This is because when combining like terms, we add or subtract the coefficients of terms with the same variable (in this case, x^2). The coefficient of x^2 in the first term is 3, and in the second term is 1. Therefore, 3x^2 - x^2 simplifies to 2x^2.
Oh, isn't that just lovely? When we have 3x squared and we take away x squared, we are left with 2x squared. Just a little subtraction dance, creating beautiful mathematical harmony on our canvas.
Oh, dude, that's like basic math, right? So, 2x squared plus x squared is just 3x squared. It's like adding apples to apples, but with math. Easy peasy lemon squeezy!

x=4 or x=-4
For any x ≠ 0, x2 -10/x2 - 4 +3x/x2 - 4 LCD = x2, multiply each term by their missing element of LCD = (x4 + 10 +3x - 8x2)/x = (x4 - 8x2 + 3x + 10)/x2
