Activity 2: Quadratic Equations

The general form of a quadratic equation is:

but sometimes doesn’t look like that because some of the parts are missing or hidden!

Work in pairs:

a) Write an example of a quadratic equations with:

• a = 0 _____________________________________________________

• b = 0 _____________________________________________________

• c = 0 _____________________________________________________

b) Are you sure you can write an example of a quadratic equation with a = 0? Write a

short paragraph explaining why you can’t write a quadratic equation with a = 0.

• If a = 0 the equation ___________________________________________

____________________________________________________________

c) Sometimes a quadratic equation doesn’t look like that because is in disguise:

In disguise

In standard form

a, b and c

Move all terms

= 3x – 1

- 3x + 1 = 0

a = 1, b = -3, c = 1

to left hand side

d) Complete the table:

In disguise

In standard form

a, b and c

Move all terms

= - 5x + 3

to left hand side

Move all terms

-4x

+ 2= 5x

to left hand side
