For example, in the equation 4 divided by ½ you must enter it as 4/(1/2). Then the division 1/2 = 0.5 is performed first and 4/0.5 = 8 is performed last. If you incorrectly enter it as 4/1/2 then it is solved 4/1 = 4 first then 4/2 = 2 last. 2 is a wrong answer. 8 was the correct answer.

The name comes from "quad" meaning square, as the variable is squared (in other words x 2).. Once the equation has been  Divide by 9 and I get x = 2.

Answers, graphs, alternate forms. Powered by Wolfram|Alpha. In algebra, a quadratic equation (from the Latin quadratus for "square") is any equation that can be rearranged in standard form as ax²+bx+c=0 where x represents an unknown, and a, b, and c represent known numbers, where a ≠ 0. If a = 0, then the equation is linear, not quadratic, as there is no ax² term. Differential Equation Calculator. The calculator will find the solution of the given ODE: first-order, second-order, nth-order, separable, linear, exact, Bernoulli, homogeneous, or inhomogeneous.

This analytical method is used since it is a plane and not a slope, just the two sets of X and Y coordinates (x1 , y1) and (x2 , y2) are enough to calculate the equation of the straight line. Linear Equations in Two Variables Calculator is a free online tool that displays the value of the variables for the given linear equation. BYJU’S online linear equations in two variables calculator tool make the calculation faster, and it displays the variable values in a fraction of seconds. Calculator just tries to balance the equation. It cannot predict products.
