This is a tutorial on just how to usage the Algebra Calculator, a step-by-step calculator because that algebra.
Solving EquationsFirst walk to the Algebra Calculator key page. In the Calculator"s message box, girlfriend can get in a math problem that you desire to calculate. Because that example, shot entering the equation 3x+2=14 right into the message box. After you enter the expression, Algebra Calculator will publish a step-by-step explanation of exactly how to settle 3x+2=14.
ExamplesTo see much more examples of troubles that Algebra Calculator understands, visit the instances page. Feel free to try them now.
Math SymbolsIf you would like to produce your very own math expressions, right here are some symbols that Algebra Calculator understands: + (Addition)- (Subtraction)* (Multiplication)/ (Division)^ (Exponent: "raised to the power")
GraphingTo graph an equation, enter an equation that starts with "y=" or "x=". Right here are some examples:y=2x^2+1,y=3x-1,x=5,x=y^2. Come graph a point, go into an notified pair through the x-coordinate and y-coordinate be separate by a comma, e.g., (3,4). To graph two objects, simply place a semicolon in between the two commands, e.g., y=2x^2+1; y=3x-1.
PolynomialsAlgebra Calculator have the right to simplify polynomials, yet it only supports polynomials comprise the variable x. Below are some examples:x^2 + x + 2 + (2x^2 - 2x),(x+3)^2.
Evaluating ExpressionsAlgebra Calculator can evaluate expressions that contain the change x. To evaluate an expression containing x, enter the expression you want to evaluate, adhered to by the
You are watching: (x+1)(x-1)
3 evaluates the expression 2x for x=3, i beg your pardon is same to 2*3 or 6. Algebra Calculator can also evaluate expressions that contain variables x and y. To advice an expression comprise x and also y, enter the expression you want to evaluate, followed by the
sign and also an ordered pair containing your x-value and y-value. Right here is an example evaluating the expression xy in ~ the point (3,4): xy
Checking answers For solving EquationsJust together Algebra Calculator can be used to evaluate expressions,Algebra Calculator can likewise be provided to check answers for addressing equations include x. As an example, mean we resolved 2x+3=7 and got x=2. If we want to plug 2 earlier into the original equation to examine our work, we have the right to do so: 2x+3=7
2. Since the prize is right, Algebra Calculator reflects a green equals sign. If we instead try a value that doesn"t work, to speak x=3 (try 2x+3=7
3), Algebra Calculator shows a red "not equals" authorize instead. To check response to a system of equations include x and also y, go into the two equations separated by a semicolon, adhered to by the
