- In mathematics, to solve an equation is to find its solutions, which are the values (numbers, functions, sets, etc.) that fulfill the condition stated by the equation, consisting generally of two expressions related by an equality sign.
- Solve System of Linear Equations Using solve Use solve instead of linsolve if you have the equations in the form of expressions and not a matrix of coefficients. Consider the same system of linear equations.
- A quadratic equation is a polynomial equation of degree 2. The ''U'' shaped graph of a quadratic is called a parabola. A quadratic equation has two solutions. Either two distinct real solutions, one double real solution or two imaginary solutions. You can see from the graph that there are two x
- We have to solve the simultaneous equation. y^2 - 4xy + 4y = 1(1) 3x^2 - 2xy = 1(2) We see that it is not possible to isolate x in terms of y or y in terms of x using any of the equations.
