Describe how to derive the quadratic formula from a quadratic equation in standard form

The quadratic formula is derived from a quadratic equation in standard form when solving for x by completing the square. The steps involve creating a perfect square trinomial, isolating the trinomial, and taking the square root of both sides. The variable is then isolated to give the solutions to the equation.

Step-by-step explanation:

:)

Firstly we learn the standard quadratic equation,

ax²+bx+c=0

where a,b,c are real numbers.

Now solve the quadratic equation using the Complete the square method.

Rewriting part of the equation as a perfect square trinomial. If you complete the square on the generic equation ax² + bx + c = 0 and then solve for x,

ax²+bx=-c

x² + =-c

add both the side

x² + +

`

take square root both the side

the equivalent expression are always the hardest ones but you look at the gcf also

step-by-step explanation:

hi there!

1. define: accuracy

a) how close a measured value is to the actual (true) value.

hope this : )
