Question

state and probe quadretic formula?​

Answer 1

Answer:

Deriving the Quadratic Formula

is actually derived using the steps involved in completing the square. It stems from the fact that any quadratic function or equation of the form y = a x 2 + b x + c y = a{x^2} + bx + c y=ax2+bx+c can be solved for its roots.

Answer 2

Step-by-step explanation:

The proof is done using the standard form of a quadratic equation and solving the standard form by completing the square. Divide both sides of the equation by a so that you can complete the square. Add these two and raise everything to the second. The + - between the b and the square root sign means plus or negative
