The point-slope form:
- given point
- given slope
The standard form:
<em>use distributive property</em>
<em>add 
to both sides</em>
<em>subtract 
from both sides</em>
<em>change the signs</em>
Answer:
Two complex roots.
Step-by-step explanation:
F(x)=2x^4 +5x^3 - x^2 +6x-1
is a polynomial in x of degree 4.
Hence F(x) has 4 roots. There can be 0 or 2 or 4 complex roots to this polynomial since complex roots occur in conjugate pairs.
Use remainder theorem to find the roots of the polynomial.
F(0) = -1 and F(1) = 2+5-1+6-1 = 11>0
There is a change of sign in F from 0 to 1
Thus there is a real root between 0 and 1.
Similarly by trial and error let us find other real root.
F(-3) = -1 and F(-4) = 94
SInce there is a change of sign, from -4 to -3 there exists a real root between -3 and -4.
Other two roots are complex roots since no other place F changes its sign

3^2 + ---------- * (8). This evaluates to 9 + 4 * 8 ), or 9+32, or 41.

Note the importance of applying Order of Operations rules correctly here.
First
Mutliply -2 and -3
Then
Add 4+6+5
Finally
4+6=10
And then
10+5=15

Discussion
9 with a sister
13 with a brother
7 with neither.
The total is 29 so you are counting some siblings twice. There are 29 - 25 students that have both, so 4 students have both.
P(brother and sister) = 4/25
P(brother and sister) = 0.16
Answer
P = <u>0.16</u>
