# Resolve: 1) use the quadratic formula to evaluate 2X^2 - 3X + 9=0. 2) Add 1/7 + 1/3 + 2. 3) Calculate 1/7 / 7. Is it = 1 or 1/49? Which is correct

Resolve:

1) use the quadratic formula to evaluate 2X^2 - 3X + 9=0.

2) Add 1/7 + 1/3 + 2.

3) Calculate 1/7 / 7. Is it = 1 or 1/49? Which is correct and why?

4) Calculate 1/7/ (1/2).

5) Calculate 2/ (1+ sqrt(3)) (sqrt is the square root function).

1) use the quadratic formula to evaluate 2X^2 - 3X + 9=0.
Solution: As the given equation is 2X^2 - 3X + 9=0
Now we know that the standard form of quadratic equation may be given as
aX 2 + bx + c =...
