§5.5 solving quadratic equations - the follow up!

This Lesson corresponds to:

exercises 35 until 37, so

the last tasks from the paragraph.

Let's first look back shortly at the first part of the paragraph.

Task 1:

1st   Copy this task in your Notebook

2nd Solve it.

Choose the right answer here:

1. x=5
2. x=√​5​​​,or,x=−√​5​​​
3. x=5,or,x=−5
4. x=√​5​​​

Task 2:

Do this task in the same way:

1st:     Copy the task

2nd:   Work it out

My CALCULATION:

Choose the good answer:

1. 2 or -2
2. not possible
3. root 2 or -root 2
4. root 2

Finally about the exercises 36 until 37!

In the quadratic equations all of a sudden 

BRACKETS appear...

Solving such a task is not very different from the others.

Now a CARD is placed over p - 4 !
