The first step for deriving the quadratic formula from the quadratic equation, 0 = ax2 + bx + c, is shown.
mote1985 [20]

Answer:

The first step for deriving the quadratic formula from the quadratic equation, 0 = ax2 + bx + c, is shown.

\: first the formula of quadratic equation  \:  =  - b ≠ \:  \sqrt{ \frac{ \:  {b  }^{2}  - 4ac}{ \: 2a} }

let's begin to solve this equation,,,

ax²  + bx + c = 0  \\ ax² + bx + c =0  \\  {x}^{2}  +  \frac{b}{a}  \:  + \frac{ {b}^{2} }{2a}  =  \frac{b2}{a}  -  \frac{c}{a}  \\ x +  \frac{ {b}^{2} }{2a}  =  -  \frac{ {b}^{2} }{2a}  -  \frac{c}{a}

<h3>MORE BASIC INFORMATION </h3>

an equation having the maximum power of the variable equal to is called the quadratic equation the general form of quadratic equation is ax² + bx +c =0 where a,b,c are real numbers a ≠0 x is variable •

a quadratic equation can be solved by two method by factorization and by formula

by factorization a quadratic equation can be solved by factorization only when the product AC can be divided into two such part that it had the sum of the difference of the two part is equal to b

by the formula of quadratic equation can be solved by \ - }

x =  \frac{ - b \sqrt{ {b}^{2} - 4ac } }{2a }  \\ root \: of \: equation \:  {ax}^{2}  + bx + c = 0 \\  - b -  \sqrt{ \frac{ {b}^{2}  - 4ac}{2a} }
