WebbTo simplify your expression using the Simplify Calculator, type in your expression like 2 (5x+4)-3x. The simplify calculator will then show you the steps to help you learn how to simplify your algebraic expression on your own. Typing Exponents Type ^ for exponents like x^2 for "x squared". Here is an example: 2x^2+x (4x+3) WebbSolution: x squared equals x multiplied by itself. In algebra , x multiplied by x can be written as (x) × (x) or x 2. So, x squared = x 2. Then, x squared plus x squared = x 2 + x 2 = 2x 2. Thus, x squared plus x squared is x 2 + x 2 = 2x 2. What is x squared plus x squared? Summary: x squared plus x squared is 2x 2. hill\u0027s food shelter love

WebbWe will make our imaginary number (i) equal to -1. The sum of squares formula we will use to factor x^2+4 with our imaginary number is as follows: a 2 + b 2 = (a + bi) • (a − bi) We start by setting up our problem in mathematical terms like this: x 2 + 4. As you can see, our problem does not look like the left side of the formula, so first ... WebbThe square root of a number x is a number, which, when multiplied by itself, results in x. Symbolically, it is written as follows: Square root of x = x = x 1 / 2. The square of the square root of x is x itself. For example, ( 6) 2 = 6. … Webb18 feb. 2012 · Best Answer. Copy. x2 - 4 is a special expression that is referred to as a difference of squares. Whenever an expression is in the format: a2 - b2. it can be factored out as: (a + b) (a - b) In the case of x2 + 4, that would be: (x + 2) (x - 2) hill\u0027s general plumbing services inc
