Calculate the squared value of a number such as n². Square numbers input as whole numbers or integers or decimal numbers or scientific E notation that are either positive or negative.
The solve for x calculator allows you to enter your problem and solve the equation to see the result. Solve in one variable or many.
x Squared: Definition. For any variable x, x squared or $x^2$ is a mathematical notation that refers to a number being multiplied by itself. It represents the expression “$x \times x$” or “x times x”. x squared symbol is $x^2$.
Solve for x in math means finding the value of x that would make the equation true.
Starting with a quadratic equation in standard form, ax² + bx + c = 0 Divide each side by a, the coefficient of the squared term. Subtract the constant term c/a from both sides. Add the square of one-half of b/a, the coefficient of x, to both sides.
Squaring a negative number multiplies it by itself, meaning two minus signs that cancel; e.g. (−3)² = 3² = 9. The rule is to cancel pairs of minus signs.
x squared is a notation that is used to represent the expression \(x\times x\). i.e., x squared equals x multiplied by itself. In algebra, \(x\) multiplied by \(x\) can be written as \(x\times x\) (or) \(x\cdot x\) (or) \(x\, x\) (or) \(x(x)\)
