To write the given quadratic equation to its vertex form, we first form a perfect square.
x² - 2x + 5 = 0
Transpose the constant to other side of the equation,
x² - 2x = -5
Complete the square in the left side of the equation,
x² - 2x + (-2/1(2))² = -5 + (-2/1(2))²
Performed the operation,
x² - 2x + 1 = -5 + 1
Factor the left side of the equation,
(x - 1)² = -4
Thus, the vertex form of the equation is,
<em> (x-1)² + 4 = 0</em>

Answer:
-3,7,17,27,37,47,57,67,77,87,97,107
Step-by-step explanation:
You add 10 to -3 which gives you 7. You continue adding. This sequence goes on forever. You just keep adding 10.
I hope this helps!
300% is the equivalent of * 3, so, 1.5 x 3 = 4.5. She would sell her bracelets at $4.50.
