By setting y = 0 in the equation and solving for x, the resulting x values are the x-intercepts where the parabola crosses the x-axis. How to Find the VertexThe general expression f(x) = ax² + bx + c is known as the standard form of a quadratic equation. But, you can also ...
The roots of a quadratic function are the x-intercepts, which are the points where the parabola crosses the x-axis. The y-coordinate of points lying on the x-axis is zero. Therefore, to find the roots of a quadratic function, we make f(x) = 0, and solve the equation. A quadratic ...
A quadratic function f(x) = ax2+ bx + c can be easily converted into the vertex form f(x) = a (x - p)(x - q) by using the values of p and q (x-intercepts) bysolving the quadratic equationax2+ bx + c = 0. Example:Convert the quadratic function f(x) = x2- 5x + 6 ...

They are also called the x-intercepts of the quadratic equation when solving it graphically. How does one find the roots of a quadratic equation? To find the roots of a quadratic equation, one must solve the equation algebraically using the quadratic formula. One can also find the roots ...
The given quadratic equation is 2x2+ 9x + 7 = 0. Hence the required equation having reciprocal roots is 7x2+ 9x + 2 = 0. Method 2:From the given equation, α + β = -9/2 and αβ = 2/7. The new equation should have its roots to be 1/α and 1/β. ...
