Question

What is the first step in solving quadratic equations by finding the square root

Answer 1

For this case we assume that we have a polynomial of the form:

$ax ^ 2 + bx + c$

To solve the polynomial, we use the quadratic equation:

$x = \frac {-b \pm \sqrt {b ^ 2 - 4ac}} {2a}$

To solve this equation, the first step is to solve the determinant.

The determinant is given by:

$D = b ^ 2 - 4ac$

Answer:

The first step is to solve the determinant.

$D = b ^ 2 - 4ac$
