Simplification is the process of replacing a mathematical expression by an equivalent one that is simpler (usually shorter), according to a well-founded ordering. Examples include:
The roots of the quadratic function y = 1 / 2 x 2 − 3x + 5 / 2 are the places where the graph intersects the x-axis, the values x = 1 and x = 5. They can be found via the quadratic formula. In elementary algebra, the quadratic formula is a closed-form expression describing the solutions of a quadratic equation.
In mathematics, an algebraic expression is an expression built up from constants (usually, algebraic numbers) variables, and the basic algebraic operations: addition (+), subtraction (-), multiplication (×), division (÷), whole number powers, and roots (fractional powers).

Philadelphia 76ers' Joel Embiid looks over the court after an NBA basketball game against the Memphis Grizzlies, Saturday, Nov. 2, 2024, in Philadelphia.
In the case of two nested square roots, the following theorem completely solves the problem of denesting. [2]If a and c are rational numbers and c is not the square of a rational number, there are two rational numbers x and y such that + = if and only if is the square of a rational number d.
If there are like terms in an expression, you can simplify the expression by combining the like terms. We add the coefficients and keep the same variable. 4 x + 7 x + 2 x = 15 x {\displaystyle 4x+7x+2x=15x}
