Forms of Quadratic equations
Please help me out

Standard form:

1. y = x² - 4x - 5

2. y = x² - 2x - 8

3. y = x² + 4x - 21

4. y = x² + 12x + 20

5. y = x² + 8x + 12

6. y = x² + 4x + 3

7. y = x² - 8x + 7

8. y = x² - 6x + 8

9. y = x² + 10x - 11

Vertex form:

1.

2.

3.

4.

5.

6.

7.

8.

9.

Factored form

1. (x + 1) (x - 5)

2. (x + 2) (x - 4)

3. (x - 3) (x + 7)

4. (x + 10) (x + 2)

5. (x + 6) (x + 2)

6. (x + 3) (x + 1)

7. (x - 7) (x - 1)

8. (x - 2) (x - 4)

9. (x + 11) (x - 1)

NB: I am skipping the vertex form since I haven't heard of it before.
