I'm assuming you meant:

$tan^{2}x + tanx - 30 = 0$
Let $u = tan(x)$

Thus, we can rewrite it into a quadratic.

$u^{2} + u - 30 = 0$
$(u + 6)(u - 5) = 0$
$u = -6 or u = 5$

Hence, $tan(x) = -6$ or $tan(x) = 5$
$x = tan^{-1}(-6)$ or $x = tan^{-1}(5)$

Rewriting it in general form, we get:
$x = \pi \cdot n + tan^{-1}(5), n \in Z$
$x = \pi \cdot n - tan^{-1}(6), n \in Z$

From there, you can find your solutions from $[0, 2\pi)$

Someone plz help I need this answer quick !

The answer is 5 months, with the cost of $85. You can find this answer by first writing the charges as 12x + 25 and 10x + 35. Then, you set them equal to each other and solve to find x, which is the number of months.
12x + 25 = 10x + 35
- 10x
2x + 25 = 35
- 25
2x = 10
÷ 2
x = 5

Now that we know what x is, we can substitute it in and get 10(5) + 35 = 50 + 35 = 85.
I hope this helps!
