Trinomial. Quadratic equation. The values of x that satisfy the equation are called solutions of the equation, and roots or zeros of the expression on its left-hand side. A quadratic equation has at most two solutions. If there is only one solution, one says that it is a double root.
The quadratic formula tells us that if we have a quadratic equation in the form ax squared plus bx plus c is equal to 0, so in standard form, then the roots of this are x are equal to negative b plus or minus the square root of b squared minus 4ac, all of that over 2a.
The simplification calculator allows you to take a simple or complex expression and simplify and reduce the expression to it's simplest form. The calculator works for both numbers and expressions containing variables.
