Today we corrected HW questions Ex. 2.5 Simplifying Fractions and did Q.20.

We then revised first year Sets.

HW: Test yourself 2 Q. 1-2

Today we continued with factorising quadratic expressions Section 2.4 (see notes below)

There are two examples of this explained in the video here (time 4:39 to 9:43).

HW: Ex. 2.4 Q.46-54 (as below)

We corrected HW and looked at the last example in 2.3 Difference of two squares factorising.

We then introduced Quadratic Factors. HW: Ex. 2.4 Q. 1-10 as below.

Today tests were rwe continued factorising using the Difference of Two Squares method from Ex. 2.3

HW: Ex.2.3 Q.19 -27

Today we corrected HW and did more examples of Factorising by grouping (section 2.2) we then started Factorising using the Difference of two squares (DOTS) (Section 2.3)

In the second class we had a test. The questions are all explained in videos on this site.

HW Ex. 2.3 Q.1-15

In the first class we corrected the hw questions.

We then looked at examples of solving double inequalities.

HW Ex. 1.7 Solve Q.21-25

Today we started by correcting the HW from Ex.1.6 on Number lines

We then introduced Section 1.7 Solving Inequalities

HW: Ex. 1.7 Q.11-15 Solve and show your answer on a number line.
