Many chemistry problems result in equations of the form
Gnom [1K]

Answer:

When this equation is solved, the two values of the unknown are 0.0643 and -0.082

Explanation:

Given

1.77 * 10^{-2} = \frac{x^2}{0.298 - x} --- the actual equation

Required

The values of x

We have:

1.77 * 10^{-2} = \frac{x^2}{0.298 - x}

Cross Multiply

1.77 * 10^{-2} * (0.298 - x)= x^2

Multiply both sides by 100

1.77  * (0.298 - x)= 100x^2

Open bracket

0.52746 - 1.77x= 100x^2

Rewrite as:

100x^2 + 1.77x - 0.52746 =0

Using quadratic formula:

x = \frac{-b \± \sqrt{b^2 - 4ac}}{2a}

Where:

a = 100; b = 1.77; c = -0.52746

So, we have:

x = \frac{-1.77 \± \sqrt{1.77^2 - 4*100*- 0.52746 }}{2*100}

x = \frac{-1.77 \± \sqrt{214.1169}}{2*100}

x = \frac{-1.77 \± 14.63}{200}

Split

x = \frac{-1.77 + 14.63}{200}\ or\ x = \frac{-1.77 - 14.63}{200}

x = \frac{12.86}{200}\ or\ x = \frac{-16.40}{200}

x = 0.0643\ or\ x = -0.082
