Answer 1

Answer:

there are 3 methods

1. splitting the middle term
2. complete the square method
3. quqdratic formula....

Answer 2

Step-by-step explanation:

There are equations that can’t be reduced using the above two methods. For such equations, a more powerful method is required. A method that will work for every quadratic equation. This is the general quadratic equation formula. We define it as follows: If ax2 + bx + c = 0 is a quadratic equation, then the value of x is given by the following formula:

Quadratic Formula

Just plug in the values of a, b and c, and do the calculations. The quantity in the square root is called the discriminant or D. The below image illustrates the best use of a quadratic equation
