Answer:
The question you provided seems to contain a mix of mathematical expressions and notation. Let's break it down and address each part separately:
1. x² - 1: This is a quadratic expression. It represents a polynomial with a degree of 2, where the variable x is squared and then subtracted by 1.
2. *+1x²-3x+2²: It appears to be an incomplete expression. There's an asterisk (*) at the beginning, which could indicate multiplication. However, the rest of the expression doesn't follow a clear mathematical pattern. If you have the complete expression or any specific question related to it, please provide more information.
3. 10. a) lim: The number 10 followed by "a) lim" seems to suggest a limit problem. However, the specific function or equation is missing. To solve a limit problem, we need to know the function or expression and the point at which we are evaluating the limit.
4. 7+x+x² / 1- 2-x-3x²: This is a rational expression involving polynomials. It represents the fraction of the quadratic expression 7+x+x² divided by the quadratic expression 1-2x-3x². To simplify or evaluate this expression further, we would need more specific instructions, such as finding the value when x is equal to a particular number.
5. 6) lim: Similar to the previous point, the number 6 followed by "lim" suggests a limit problem. However, the function or expression is missing. To solve a limit problem, we need the function or expression and the point of evaluation.
6. B) lim: Again, we have a limit problem denoted by "B) lim". However, there is no specific function or expression provided. To solve a limit problem, we need the function and the point of evaluation.
7. 3-0: This is a simple subtraction operation. Subtracting 0 from 3 gives us the result of 3.
8. sin 6x: This is a trigonometric expression. It represents the sine function applied to the value of 6x. The result will depend on the value of x.
9. tg4x: This seems to be a typo or abbreviation. If you meant "tan 4x," it represents the tangent function applied to the value of 4x. Similarly to the previous expression, the result will depend on the value of x.
i hope this helps you. sorry if the answer is not as you have wished.
