Assignments

The following assignments are about solving quadratic equations. One method to solve this type of equation is the use of the abc-method. This may not always be possible and then other methods such as factorization (Quadratic equations (factorizing)) are possible.

1. Solve:

x^2+7x+12=0

Solution

2. Solve:

-x^2+5x-6=0

Solution

3. Solve:

x^2-x-56=0

Solution

4. Solve:

3x^2+x-2=0

Solution

5. Solve:

4x^2+8x=0

Solution

6. Solve:

4x^2+20x+25=0

Solution

7. Solve:

x^2+x+25=0

Solution

8. For which value(s) of p does the equation:

x^2-2x+p=0

have two different solutions x.

Solution

9. For which value(s) of q does the equation:

qx^2-2x+q=0

have two coinciding solutions x.

Solution

10. For which value(s) of p does the equation::
