Exercise
$\frac{\left(x+1\right)\left(x-1\right)}{x^2+1}>2$
Step-by-step Solution
Learn how to solve problems step by step online. Solve the inequality ((x+1)(x-1))/(x^2+1)>2. The sum of two terms multiplied by their difference is equal to the square of the first term minus the square of the second term. In other words: (a+b)(a-b)=a^2-b^2.. Moving the denominator multiplying to the other side of the inequation. Multiply the single term 2 by each term of the polynomial \left(x^2+1\right). Grouping terms.
Solve the inequality ((x+1)(x-1))/(x^2+1)>2
Final answer to the exercise
$x>\sqrt{3}i$
