(08.03 MC) Solve for x using the Quadratic Formula: x2 - 6x + 9 = 0
-bt/6².
-4ac
X=
2a
A. x = 6
B. x = 3
C. x=1
D. x=0

B. x = 3

Step-by-step explanation:

You really don't need to quadratic formula for this. It would take too much time. Instead, factor out the equation:

(x -3)(x - 3) = 0

Once you found that, you should see that your roots will equal to 3.

Answer:

solution,

Rewrite x^2-6x+9 in the form a^2-2ab+b^2 where a=X and b=3.

Use square of difference,

Take the square root of both sides

Add 2 to both sides,

hope this helps..

Good luck on your assignment..
