We have the roots 1/2 and 4/3 and we need to write a quadratic equation of the form 
using those roots. Since we know that 1/2 and 4/3 are roots of our quadratic, we can equate each root to 
and factor backwards:
and 
and 
and 
Now we can multiply the left sides of our equations to get our quadratic:
W can conclude that the quadratic equation with roots 1/2 and 4/3 is
.
