Answer:
r = -6, -1
Step-by-step explanation:
r^2 + 7r+6 =0
Factor
What 2 numbers multiply to 6 and add to 7
6*1 =6
6+1 =7
(r+6) (r+1) =0
Using the zero product property
r+6 =0 r+1 =0
r = -6 r=-1
V=<12,5>
Magnitude
|v| = sqrt(12^2+5^2) = 13
Direction
theta
= atan2(5,12)
= atan(5/12)
= 22.62 degrees
X^2 - 5x - 14 = 0
what multiplies to negative 14 and adds to negative 5? -7 and positive 2.
(x - 7) (x + 2) = 0
Lesser x = -2
Greater x = 7
