50 PTS Please do not steal or I will report Can someone explain how the quadratic equation works with an example!

The quadratic formula helps us solve any quadratic equation. First, we bring the equation to the form ax²+bx+c=0, where a, b, and c are coefficients. Then, we plug these coefficients in the formula: (-b±√(b²-4ac))/(2a) .The four methods of solving a quadratic equation are factoring, using the square roots, completing the square and the quadratic formula.

Step-by-step explanation: 6x² + 11x - 35 = 0.

2x² - 4x - 2 = 0.

-4x² - 7x +12 = 0.

20x² -15x - 10 = 0.

x² -x - 3 = 0.

5x² - 2x - 9 = 0.

3x² + 4x + 2 = 0.

-x² +6x + 18 = 0.
