Answer:

X would be -5/2 and 1

Explanation:

The quadratic formula is (-b±√(b^2-4ac))/2a. By substituting the values in, we get the expression (-3±√(3^2-4(2)(-5))/2(2). By Simplifying, we get (-3±√(9+40))/4. More simplification: (-3±√(49))/4. Even more simplification: (-3±7)/4. The expression now splits into two parts, (-3-7)/4, and (-3+7)/4. The first expression becomes -10/4, which simplified is -5/2. The second expression becomes 4/4, which simplifies to 1. Therefore, your answers are x=1, -5/2.

Hope this helps!
