I assume you are asking to solve:
-2x^2 + 3x - 9 = 0
So first, this equation does not have real roots.
It only has 2 complex roots.
The roots are:
3/4 * (1-i√7) and 3/4 * (1+i√7)
10 1/4 / 151 3/16 = 4/59
Have a great day :)
Answer:
B. 108
Step-by-step explanation:
a straight angle is 180 degrees.
180-72=108
The answer to this is -11/12
Answer:
3√2
Step-by-step explanation:
this is called 45° ~ 45°~ 90° special triangle
the right angles has a length of x while hypotenuse has x√2
since in this triangle the given right sides' length = 3, hypotenuse must be = 3√2
