Hey can you please help me posted picture of question

Dmitry_Shevchenko [17]

Answer:
The solutions are:
$\frac{3 + i}{2}$ and $\frac{3 - i}{2}$

Explanation:
The general form of the quadratic equation is:
ax² + bx + c = 0
The given equation is:
2x² - 6x + 5 = 0

By comparison:
a = 2
b = -6
c = 5

Now, to get the solutions of the equation, we will have to use the quadratic formula shown in the attached image.

By substituting in the formula, we would find that:
either x = $\frac{6 + \sqrt{(-6)^2 - 4(2)(5)} }{2(2)} = \frac{3 + i}{2}$

or x = $\frac{6 - \sqrt{(-6)^2 - 4(2)(5)} }{2(2)} = \frac{3 - i}{2}$

Hope this helps :)

Evaluate (x + y)0 for x = -3 and y = 5. A. -1/2 B. 0 C. 1 D. 2

Anastasy [175]

Hello there! With the values of "x" and "y", they fill in the parenthesis. -3 + 5 is 2, because adding into a negative makes the number go up, or just simply subtracting 3 from 5 works as well. However, there is a 0 beside it, so we raise 2 to the 0 power. Anything that is raised to the 0 power is always equal to 1. And there is no other part of the question, so 1 is our answer. The answer is C: 1.
