Chapter 1: Q58. (page 25)

Solve each equation or formula for the specified variable.
$x = \frac{- b}{2 a}$ , for a.

Short Answer

Expert verified

The required answer is $a = - \frac{b}{2 x}$ .

Step by step solution

Step 1- Multiply 2a on both sides

Perform multiplication of 2a on both the sides of equation.

$\begin{matrix} 2 a (x) = 2 a (\frac{- b}{2 a}) \\ 2 a x = - b \end{matrix}$

– Isolate the variable a

Perform division of 2x on both the sides of the equation.

$\begin{matrix} \frac{2 a x}{2 x} = \frac{- b}{2 x} \\ a = - \frac{b}{2 x} \end{matrix}$

Step 3- Make the conclusion

As the variable a is isolated so the value equivalent to it represents its value.
