Answer:

Hello,

- 6 (x - 2)² - 1

Step-by-step explanation:

- 6 x² + 24 x - 25 = - 6 (x² - 4 x) - 25

= - 6 ( (x - 2)² - 4) - 25

= - 6 (x - 2)² + 24 - 25

= - 6 (x - 2)² - 1

Answer:

5 hours

Step-by-step explanation:

Given

$y = 420 + 72x$ --- Revenue

$y = 24x^2 + 180$ --- Overhead cost

Required

Determine the hours for break even

To do this, we simply equate both expressions as follows:

$24x^2 + 180 = 420 + 72x$

Collect Like Terms

$24x^2 - 72x + 180 - 420 = 0$

$24x^2 - 72x -240 = 0$

Divide through 24

$x^2 - 3x - 10 = 0$

Expand:

$x^2 -5x + 2x -10 = 0$

Factorize:

$x(x -5) + 2(x -5) = 0$

$(x + 2)(x -5) = 0$

$x + 2 = 0\ or\ x - 5 = 0$

$x = -2\ or\ x = 5$

But x can't be negative because it represents time.

<em>So, x = 5 hours</em>
