Answer:

$\huge\boxed{\sf Option \ B}$

Step-by-step explanation:

$\displaystyle x^2+\frac{bx}{a} =\frac{-c}{a}$ --------------------(1)

to find the b² for the expression on the left.

Take the expression

$\displaystyle x^2 + \frac{bx}{a}$

<u>We can also write it as:</u>

$\displaystyle (x)^2 + 2(x)(\frac{b}{2a} )$

According to the formula $a^2+2ab+b^2$ , the b of this expression is $\displaystyle \frac{b}{2a}$ . So,

b² will be:

$\displaystyle =(\frac{b}{2a} )^2\\\\=\frac{b^2}{4a^2}$

So, we will add $\displaystyle \frac{b^2}{4a^2}$ to both sides in Eq. (1)

For STEP 4, the equation will become:

$\displaystyle x^2+\frac{bx}{a} + \frac{b^2}{4a^2} = \frac{-c}{a} + \frac{b^2}{4a^2}$

$\rule[225]{225}{2}$
