Solve for x: −2(x − 2)2 + 5 = 0
Licemer1 [7]

Option A

The values of x are 3.58 or 0.42

<u>Solution:</u>

Given, equation is -2(x-2)^{2}+5=0

We have to solve for the x and choose from the options given,

Now, take the equation,

\begin{array}{l}{\rightarrow-2(x-2)^{2}+5=0} \\\\ {\rightarrow-2(x-2)^{2}=-5}\end{array}

Negative sign cancels on both sides

\begin{array}{l}{\rightarrow 2(x-2)^{2}=5} \\\\ {\rightarrow(x-2)^{2}=\frac{5}{2}}\end{array}

Taking square root on both sides, we get

\begin{array}{l}{\rightarrow x-2=\sqrt{\frac{5}{2}}} \\\\ {\rightarrow x-2=\pm 1.58} \\\\ {\rightarrow x=2 \pm 1.58}\end{array}

\begin{array}{l}{\rightarrow x=2+1.58 \text { or } 2-1.58} \\\\ {\rightarrow x=3.58 \text { or } 0.42}\end{array}

Hence, the values of x are 3.58 or 0.42, so option A is correct.

stepladder [879]

Note: 6 employees means half of the employees contributed $7.75 each.


6 x $7.75 = $46.50.


To find how much money remains to be collected, subtract $46.50 from $100.


So, $100 - $46.50 = $53.50 is the answer.
