Solve the following quadratic by
completing the square.
y = x2 - 6x + 7

Sagot :

Answer:

x = 5  or   x = 1

Step-by-step explanation:

 x² - 6x + 7 = 0

x² - 6x = -7

x² - 6x + 9 = -7 + 9      1/2 of the x term than square it and add it the both sides.

(x - 3)(x - 3) = 2

( x -3)² = 2

[tex]\sqrt{(x - 3)^2[/tex] = [tex]\sqrt{2}[/tex]

(x -  3) = ± 2

x - 3 = 2  or  x - 3 = -2

x = 5     or  x = 1
