Let us graph the equation given and see what the x-intercepts are. These are points where the line intercepts the x-axis. <em>See attached</em>.

This means our x-intercepts are at about (-2.414, 0) and (0.414, 0).

These are also equal to $-1-\sqrt{2}$ and $-1+\sqrt{2}$

Sonja [21]

Answer:

There is a total 50 questions.

Step-by-step explanation:

Let x = total questions in the exam

Since 82% of the test was scored correctly, that means 18% of the student's exam was scored incorrectly.

With this information we can write:

$18\%x=9$ (Given that the student made 9 mistakes)

$x=9\div18\%$ (divide 18% on both sides)

$x=50$

∴ There was a total of 50 questions in the examination.
