fonz said:[itex]y = 2\sqrt{x}[/itex]
[itex]y = \frac{x^{2}}{4}[/itex]
I still have no idea how to find [itex]x[/itex]
A quadratic simultaneous equation is a system of two equations that contain at least one quadratic term. This means that at least one variable in each equation is squared.
To solve a quadratic simultaneous equation, you can use substitution or elimination. In substitution, you solve one equation for one variable and then substitute that value into the other equation. In elimination, you manipulate the equations to eliminate one variable and then solve for the remaining variable.
Yes, a quadratic simultaneous equation can have more than two solutions. This happens when the two equations intersect at more than two points. These points are known as the solutions or roots of the equations.
A quadratic simultaneous equation contains at least one quadratic term, while a linear simultaneous equation only contains linear terms (no squared or higher order terms). This means that the solutions to a quadratic simultaneous equation may be more complex and can include imaginary numbers, while the solutions to a linear simultaneous equation will always be real numbers.
Yes, it is possible for a quadratic simultaneous equation to have no solutions. This happens when the two equations do not intersect at any point, meaning there is no solution that satisfies both equations simultaneously. This can also happen when the two equations are parallel and never intersect.
