To solve this polynomial equation, we first factor the left side.
To factor x² + 8x + 12 = 0, look for factors of 12 that add to 8.
These factors are 6 and 2 so we have (x + 6)(x + 2) = 0.
So either x + 6 = 0 or x + 2 = 0 and solving for
x in each equation, our answer is {-6, -2}.
The rate(speed) is 1 3/5
We can use the distance formula to solve:
d= rt
D= 4/5
T=1/2 hr
Substitute
4/5= 1/2t
Multiply 2 on both sides
2* (4/5)=(1/2)t * 2
8/5=t
We can simplify this to 1 3/5
