Can you simplify x 2. In an algebraic fraction, only factors can be cancelled.

Can you simplify x 2 (x + 1) (x^2 - 2x + 1)/(x^2 - 1) = (x - 1)^2/((x - 1)(x + 1)) So (x - 1)^2 and (x - 1) simplify each other. This is essentially doing the distributive property twice. Our math solver supports basic math, pre-algebra, algebra, trigonometry, calculus and more. Use the power rule to combine exponents. There seem to me to be two aspects to this question: (1) What does "square root of x^2+4" mean? sqrt(x^2+4) is a term which when squared yields x^2+4 : sqrt(x^2+4) xx sqrt(x^2+4) = x^2 + 4 In other words t = sqrt(x^2+4) is the solution t of the equation t^2 = x^2+4 (2) Can the formula sqrt(x^2+4) be simplified? No. Simplify (x^2)/(x^(1/2)) Step 1. The value of x may vary (hence the name). 1 Answer Mena A. My Notebook, the Symbolab way.
