Step-by-step solutions» Wolfram Problem Generator» What are quadratic equations, and what is the quadratic formula? A quadratic is a polynomial of degree two. Quadratic equations form parabolas when graphed, and have a wide variety of applications across many disciplines. In physics, for exa...
We can also use the quadratic formula:We get two answers x+ and x− (one is for the "+" case, and the other is for the "−" case in the "±") that gets us this factoring:a(x − x+)(x − x−)Example: what are the roots of 6x2 + 5x − 6 ? Substitute a=6...
Quadratic Formula Examples Compute the roots of the following quadratic equation: \(3x^2 - 2x + 4 = 0\) Solution: The following equation needs to be solved: \[ 3 x^2 -2 x + 4 = 0\] This corresponds to a quadratic equation. The following formula is used to find the solutions...
Quadratic Equation Examples ax2+bx+c=0 x2−x−6=9 x2−x−6=0 Description Solve quadratic equations step-by-step Frequently Asked Questions (FAQ) How do you calculate a quadratic equation? To solve a quadratic equation, use the quadratic formula: x = (-b ±√(b^2 - 4ac)) /...
Step - 1: By comparing the given function with f(x) = ax2 + bx + c, we get a = 2, b = -8, and c = 3. Step - 2: Find 'h' using the formula: h = -b/2a = -(-8)/2(2) = 2. Step - 3: Find 'k' using the formula: k = f(-b/2a) = f(2) = 2(2)2 -...
A quadratic equation is of the form ax2 + bx + c = 0 where a ≠ 0. A quadratic equation can be solved by using the quadratic formula. You can also use Excel's Goal Seek feature to solve a quadratic equation.
What is the Quadratic Formula? The quadratic equation formula to solve the equation ax2 + bx + c = 0 is x = [-b ±√(b2 - 4ac)]/2a. Here we obtain the two values of x, by applying the plus and minus symbols in this formula. Hence the two possible values of x are [-b + ...
