Solving Quadratic Equations by Completing the Square Method
Answer:
[tex]x = 4 +\sqrt{19}[/tex] and [tex]x = 4 -\sqrt{19}[/tex]
Step-by-step explanation:
Recall:
[tex]x^2 -2ax +a^2 = (x -a)^2[/tex]
[tex]x^2 -8x = 3 \\ x^2 -8x +16 = 3 +16 \\ (x -4)^2 = 19 \\ x -4 = ±\sqrt{19} \\ x = 4 ±\sqrt{19}[/tex]
