How do you get X by itself? To get a variable by itself a combination of algebraic techniques is requiered. The distributive property, the addition and subtraction properties of equality to move all the terms containing x to one side of the equation, the multiplication and division properties of equality to eliminate any coefficients.

In the equation 2x + 3 = 7, for instance, we get x by applying mathematical operations maintaining both sides balanced. In economics, physics, mathematics, engineering, and chemistry as well as other fields, equations are extensively used to understand real world issues to provide answers.

Example: 7x and 3x are like terms because they both contain x. Combine Like Terms: Identify like terms in the expression. Add or subtract the coefficients of like terms. Rewrite the expression with combined terms. Example: Simplify 4x+5−2x+3. Combine the like terms (4x and −2x): 4x−2x=2x. Combine constants (5 and 3; 5 + 3 = 8).

2x + 3(x−3) − 6 = 0. Expand and solve: 2x + 3x − 9 − 6 = 0. 5x − 15 = 0. 5(x − 3) = 0. x − 3 = 0. Which can be solved by having x=3. Let us check x=3 using the original question: 2 × 3 3 − 3 + 3 = 6 3 − 3. Hang On: 3 − 3 = 0 That means dividing by Zero! And anyway, we said at the top that x≠3, so ... x = 3 does not ...

This polynomial is considered to have two roots, both equal to 3. One learns about the "factor theorem," typically in a second course on algebra, as a way to find all roots that are rational numbers. One also learns how to find roots of all quadratic polynomials, using square roots (arising from the discriminant) when necessary.

The equations section lets you solve an equation or system of equations. You can usually find the exact answer or, if necessary, a numerical answer to almost any accuracy you require.

An example with three indeterminates is x + 2xyz − yz + 1. Quadratic equation In mathematics, a quadratic equation (from Latin quadratus 'square') is an equation that can be rearranged in standard form as displaystyleax²+bx+c=0,, where the variable x represents an unknown number, and a, b, and c represent known numbers, where a ≠ 0.

The equation solver allows you to enter your problem and solve the equation to see the result. Solve in one variable or many.

For example the command 2x @ 3 evaluates the expression 2x for x=3, which is equal to 2*3 or 6. Algebra Calculator can also evaluate expressions that contain variables x and y. To evaluate an expression containing x and y, enter the expression you want to evaluate, followed by the @ sign and an ordered pair containing your x-value and y-value.

To solve the equation x − x + 2 x + x = 18, we first simplify the left-hand side. Combine like terms: The terms in the equation are x, − x, 2 x, and another x. x − x = 0, so we have: 0 + 2 x + x = 18; Combine the remaining terms: 2 x + x = 3 x, so we now have: 3 x = 18; Now, to solve for x, we divide both sides by 3: x = 3 18 x = 6 ...

Therefore, x 2 = x × x. The value of x 2 will depend on what x equals. If x is equal to 0, then x 2 = 0 2 = 0. However, if x has any other value (like 1, 2, or -3), then x 2 will not equal 0. Thus, x 2 does not automatically equal 0; it only equals 0 when x is 0. Hope this helps! :D

x2 is an expression that can be read "x squared" or "x to the power of two". It is equal to x times x.

What Does X2 Equal? Are you trying to figure out what x2 equals? Well, it’s a pretty simple question with a pretty simple answer. To put it simply, x2 is the same as x multiplied by itself. This means that if x is any number, then x2 is that number multiplied by itself. Let’s take a look at some examples to illustrate this concept. In mathematics, x2 means a number multiplied by itself.
