The simplified answer is A.
Answer:
A: -19
B: The equation has two complex solutions.
Step-by-step explanation:
(A) Compare
... x² +5x +11 = 0
to the form
... ax² + bx + c = 0
and you see that a=1, b=5, c=11.
The discriminat (d) is computed as
... d = b²-4ac
Putting the above values in this equation for a, b, c, we get
... d = 5² -4·1·11 = 25 -44 = -19
_____
(B) The solutions are ...
... x = (-b ±√d)/(2a) = (-5 ±√-19)/2
The square root of -19 is imaginary, so there are two complex solutions. It will be the case that the two solutions are complex whenever the discriminant is negative.
Answer:
Return on equity (ROE) = profit margin × asset turnover × financial leverage
Step-by-step explanation:
Return on equity (ROE) = profit margin × asset turnover × financial leverage
Which can be written as:
ROE = (net income÷ sales) × (sales ÷ total assets) × (total asset ÷ average shareholder equity)
