Question

Please answer each step, step by stepLeo solve the equation for C but made an error. his work is shown below. What is wrongThe error is in line___The correct solution is_____

Answer 1

Answer:

The error is in line iii

And the correct solution is;

$4c^2+1=d$

Explanation:

Given the equation;

$c=\frac{1}{2}\sqrt[]{d-1}$

Solving for d, we have;

multiply through by 2 to get;

$2c=\sqrt[]{d-1}$

then we will square both sides;

$\begin{gathered} (2c)^2=d-1 \\ 4c^2=d-1 \end{gathered}$

Adding 1 to both sides;

$4c^2+1=d$

Therefore;

The error is in line iii

And the correct solution is;

$4c^2+1=d$
