Solve for x

Mathematics
1 answer:
Ulleksa [173]3 years ago
8 0

Answer:

C. x = 1

Step-by-step explanation:

To solve this problem the best way is to use the quadratic formula. First make everything equal to 0 by adding 3 to both sides.

3x^2 - 6x + 3 = 0

The quadratic formula is: \frac{-b\pm\sqrt{b^2-4ac} }{2a}. Substitute the values of a, b, and c into the formula. Keep in mind:

  • a = 3
  • b = -6
  • c = 3

\frac{-(-6)\pm\sqrt{(-6)^2-4(3)(3)} }{2(3)} \rightarrow \frac{6\pm\sqrt{36-4(9)} }{6} \rightarrow \frac{6\pm\sqrt{0} }{6} \rightarrow \frac{1\pm0}{1} \rightarrow 1

Therefore, x = 1.

This means it was reflected across the Y axis.

The first answer is the correct one.
