2 x + 2 x − 3 x = x. Still have questions? 2x-8(5-x)=18 One solution was found : x = 29/5 = 5.800 Rearrange: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation : 2x-8(5-x)=18 One solution was found : x = 29/5 = 5.800 Rearrange: Rearrange the equation by subtracting 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. \langle 3x,3x\rangle=3x doesn't make sense, as the left-hand side is a number and the right-hand side is a function. Perhaps some of the problem is the notation.

Solve your math problems using our free math solver with step-by-step solutions. Our math solver supports basic math, pre-algebra, algebra, trigonometry, calculus and more. Toto možno zjednodušiť v roku 2007 3x 2 + 24, zatiaľ čo 3x (x 2 + 8) je možné prepísať do podoby 3x 3 + 24x, Všimnite si, že v niektorých prípadoch, ako pri premenných zlomkoch, konštanta susediaca s zátvorkami dáva možnosť vymazať faktory a nemala by sa vynásobiť.

x² + x + 4 = 0. That, now, is a quadratic equation. The x-coordinate of any point of intersection would have to satisfy this equation. discriminant = (1)² - 4(1)(4) = -15 (2x 3 + 3x 2 - x + 16) / (x 2 + 2x - 3) Solution: The dividend 2x 3 + 3x 2 - x + 16 is a polynomial of degree 3. The divisor x 2 + 2x - 3 is a polynomial of degree 2.

Free math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by-step explanations, just like a math tutor. Two numbers r and s sum up to \frac{1}{3} exactly when the average of the two numbers is \frac{1}{2}*\frac{1}{3} = \frac{1}{6}. You can also see that the midpoint of r and s corresponds to the axis of symmetry of the parabola represented by the quadratic equation y=x^2+Bx+C.
