↝ Form into
where a > 0 (Optional)
↝ Multiply -1 for both sides.
↝ Then proceed with the Quadratic Formula.

![x=\frac{-(-5)+-\sqrt{(-5)^2-4(1)(8)}}{2(1)}\\x=\frac{5+-\sqrt{25-32}}{2}\\](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B-%28-5%29%2B-%5Csqrt%7B%28-5%29%5E2-4%281%29%288%29%7D%7D%7B2%281%29%7D%5C%5Cx%3D%5Cfrac%7B5%2B-%5Csqrt%7B25-32%7D%7D%7B2%7D%5C%5C)
↝ As you can see that inside the square root, the numbers cannot be negative. Therefore, the solutions are imaginary.
↝ Solution with Real Numbers System ↝ There are no real solutions.
↝ Solution with Complex Number System ↝
![x=\frac{5+-\sqrt{25-32}}{2}\\x=\frac{5+-\sqrt{-7}}{2}\\x=\frac{5+-\sqrt{7}i }{2}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B5%2B-%5Csqrt%7B25-32%7D%7D%7B2%7D%5C%5Cx%3D%5Cfrac%7B5%2B-%5Csqrt%7B-7%7D%7D%7B2%7D%5C%5Cx%3D%5Cfrac%7B5%2B-%5Csqrt%7B7%7Di%20%7D%7B2%7D)
Therefore, the answer for Complex Number System is (5±√7i)/2
Answer:
its 2
Step-by-step explanation:
the opposite of the negative number would be a positive number and vise versa so the opposite of -2 would be 2
A = 3.5
b = 3.5
c = 2.5
d = 2.85
e = 2.6
The two unit rates that are equal are a and b
28 per 8 salads and 42 per 12 steaks have equal unit rates.
Answer:
(g + f)(x)
Step-by-step explanation:
the outputs of f(x) and g(x) will always have a sum of -1, which is h(x).
