Your image link is broken.

1) Re-arrange: 3x^2 + 4x - 2 = 0.

2) .....

3) Re-arrange: 2x^2 - 14x - 20 = 0.

Now solve each of them using the method you have been taught. You might need to go back to your class notes or textbook to review that material. If you need more help, please show what you've done and say where you get stuck. And please fix the link.
