Answer:
x = ±
Step-by-step explanation:
Given
x² - 7x + 9 = 0 ( subtract 9 from both sides )
x² - 7x = - 9
Solve using the method of completing the square
add ( half the coefficient of the x- term)² to both sides
x² + 2( - )x +
= - 9 +
(x - )² =
( take the square root of both sides )
x - = ±
= ±
( add
x = ±
=
