This formula is known as the quadratic formula. We have used a simple way toprove quadratic formulawe can put values of a, b and c from any equation and find the value of x (the variable) by directly using this formula. IB Mathematics tutors can also explain the concept of conjugate ro...
Solving a quadratic equation means determining the value (or values) of x which, when input into a quadratic function f(x), would yield 0. There are three primary methods for solving a quadratic equation: factoring, completing the square, and using the quadratic formula. Method 1: Factoring ...
How to Graph a Quadratic Function Suppose that we want to sketch the graph of a quadratic function by hand. Thanks to everything that we know about the various forms of quadratic equations, we can do this. Given the equation for a quadratic function, here are the steps to sketch its grap...

The meaning of QUADRATIC FORMULA is a formula that gives the solutions of the general quadratic equation ax2 + bx + c = 0 and that is usually written in the form x = (-b ±√(b2 — 4ac))/(2a).
Using the general quadratic formula [10], here we have a = 4, b = −7 and c = 3. Therefore: x=+7±49−488=7±18Therefore, x = 1 or x = 0.75 defines the two roots of the equation. We can now represent the function as: (x−1)(x−0.75)and this, when multiplied out...
For a equation ax^2 + bx + c = 0 we call a b c are coefficients of this equation where a is the coefficient of x^2 b is the coefficient of x c is the constant. Since 2x^2 - x = 3 can rewrite as : 2x^2 - 1x - 3 = 0 So the coefficients of this equation ...
