A quadratic equation is an equation of the form ax 2 + bx + c = 0, where a, b and c are constants. For example 3x 2 + 2x - 9 = 0 is a quadratic equation with a = 3, b = 2 and c = -9. The constants b and c can have any value including 0. The constant a can have any value except 0. This is to ensure that the equation has an x 2 term.

Click on the intersection of the x axis and the graph of the parabola to check your solutions ...In elementary algebra, the quadratic formula is a formula that provides the solution(s) to a quadratic equation. There are other ways of solving a quadratic equation instead of using the quadratic formula, such as factoring (direct factoring, grouping, AC method), completing the square, graphing and others. The quadratic formula is . In the equation ,a is the coefficient of the term, b is the coefficient of the x term, and c is the constant. Substitute 2 for a, -1 for b, and -1 for c in the quadratic formula and simplify. Method 4: Graphing. Graph y= the left side of the equation or and graph y= the right side of the equation or y=0. How to graph your problem. Graph your problem using the following steps: Type in your equation like y=2x+1. (If you have a second equation use a semicolon like y=2x+1 ; y=x+3) Press Calculate it to graph!When we solve quadratic functions, we are actually finding the roots of the equation. A root is a point where the equation is equal to zero (in algebraic terms), or where the graph crosses the x-axis (in graphical terms). Method one: Solve by factoring. Factor to solve the quadratic equation 14x 2 + 7x = 0 .
