Answer:

x = √6 or - √6

Step-by-step explanation:

equation: -7x + 6 = x² - 7x

switch sides:

x² - 7x = -7x + 6

Add 7x to both sides,

x² - 7x + 7x = -7x + 7x + 6

x² = 6

For x² = f(a) the solution are x = √f(a), -√f(a)

x = √6 , x = - √6

Answer:

-7x + 6 = x² - 7x

-7x + 7x +6 - x² = 0

0 + 6 - x² = 0

-x² + 6 = 0

-x² = (-6)

x² = 6

x = ±√6

x =√6 or x = -√6
