#### Slide 1 -Tekstslide

Deze slide heeft geen instructies

Learning Objective
At the end of the lesson, you will be able to factorize quadratic expressions and solve problems related to them.

#### Slide 2 -Tekstslide

Introduce the learning objective of the lesson and explain why it is important to be able to factorize quadratic expressions.

#### Slide 3 -Woordweb

Quadratic expressions are expressions with one or more squared variables. For example, x^2 + 2x + 1 is a quadratic expression.

#### Slide 4 -Tekstslide

Explain what quadratic expressions are and give some examples.
What is Factorization?
Factorization is the process of finding the factors of an expression. For example, the factors of x^2 + 2x + 1 are (x + 1)^2.

#### Slide 5 -Tekstslide

Define what factorization is and explain how it is related to quadratic expressions.
To factorize a quadratic expression, we need to find two expressions that multiply together to give the original expression. For example, x^2 + 2x + 1 can be factored into (x + 1)^2.

#### Slide 6 -Tekstslide

Explain the process of factoring quadratic expressions and give some examples.
Practise Questions 1
Factorize the following quadratic expression: x^2 + 6x + 9

#### Slide 7 -Tekstslide

Give students time to try the question and then provide the answer and explanation.
Practise Questions 2
Factorize the following quadratic expression: x^2 - 4x - 5

#### Slide 8 -Tekstslide

Give students time to try the question and then provide the answer and explanation.
Problem Solving Questions 1
If a quadratic expression can be factored into (x + 3)(x - 2), what are its roots?

#### Slide 9 -Tekstslide

Explain what roots are and give students time to try the question. Then provide the answer and explanation.
Problem Solving Questions 2
A quadratic expression has roots of 2 and -5. What is its factored form?

#### Slide 10 -Tekstslide

Give students time to try the question and then provide the answer and explanation.
