Step-by-step explanation:
I dont know sorry i am also bad in math
Factor the coefficients:
-12=(-1)(3)(2^2)
-9=(-1)(3^2)
3=3
The greatest common factor (GCF) is 3
Next we find the GCF for the variable x.
x^4
x^3
x^2
The GCF is x^2.
Next GCF for variable y.
y
y^2
y^3
the GCF is y
Therefore the GCF is 3x^2y
To factor this out, we need to divide each term by the GCF,
(3x^2y)(−12x4y/(3x^2y) − 9x3y2/(3x^2y) + 3x2y3/(3x^2y) )
=(3x^2y)(-4x^2-3xy+y^2)
if we wish, we can factor further:
(3x^2y)(y-4x)(x+y)
The denominator in the earnings per share formula is number of common shares outstanding.
What is the denominator used in the computation of earnings per share?
- The weighted average of the outstanding shares of common stock serves as the numerator of the earnings per share.
- The "per share" part necessitates further computation when the number of common shares changes in the middle of the year.
- The weighting of the per share part depends on how long each share number has been in circulation.
How are basic earnings per share determined?
- Basic EPS is calculated by dividing net income by the weighted average of the common shares outstanding for the relevant period.
- Preferred dividends should be removed from the net income because they are not available to common stockholders.
- Net income can also be broken down into "continuing operations" P&L and "total P&L".
