Answer:

Step-by-step explanation:

7x = x² - 8

=> x² - 7x - 8 = 0

use quadratic formula:

a = 1, b = -7, c = -8

x = $\frac{-(1)±\sqrt{(-7)^{2} - 4(1)(-8) } }{2(1)}$ <em>(pls ignore the "A" I don't know why it's showing up)</em>

=> x = $\frac{-1±\sqrt{49 + 32} }{2}$

=> x = $\frac{-1±9 }{2}$

=> x = $\frac{-1 +9}{2}$ = 4 or $\frac{-1-9}{2}$ = -5 <em>(the answer is only 4 since it's asking for the positive solution)</em>
