Question

Equation: 8 divided by

(x^{2} + x + 1) = 1

Use crossing graphs method to solve the above equation. There are 2 solutions. Round answers to 2 decimals. Provide smaller and larger value:

x = (s m a l \leq r v a l u e) x = (l a r \geq r v a l u e)

Answer 1

Step 1
8 divided by $(x^{2} + x + 1) = 1$
This means,
$8 / (x^{2} + x + 1) = 1$
Hence, $8 = x^{2} + x + 1$
Step 2
Let's plot two graphs:
$y = 8$
and $y = x^{2} + x + 1$

There are two solutions (the points of intersection):
$x = - 3.19$ (smaller value)
$x = 2.19$ ( larger value)
