Today we started 2.3 using the discriminant to discover if a quadratic curve had 

• 2 real different roots
• 1 real root (ie 2 real roots that are the same)
• No real roots (2 imaginary roots)

Class notes are uploaded (click here).

Today we looked at questions from Section 2.4 Solving problems using quadratic and linear equations (click here).

HW - Prepare for test on Thursday.

Today we corrected HW from 2.3 on Quadratic simultaneous equations (click here).

We then introduced Section 2.4 solving problems using simultaneous quadratic equations looking at Example 1 and 2 in the book..

HW: Exercise 2.4 Q. 1, 4, 7, 15

Today we corrected 1.9 Q.14 (click here)

We looked at a few examples of how to solve quadratic equations by factorising and by using the quadratic formula see Section 2.1 then we introduced Section 2.3 solving quadratic and linear simultaneous equations (click here)

HW - Section 2.3 Q. 5-7

Today we corrected simultaneous equations questions solving for x, y and z. We then looked at problems involving simultaneous equations. Class notes are uploaded (click here).

HW - Questions from section 1.9 including Q.14

Section 1.9 Solving simultaneous equations with 3 variables also called the intersection of three planes (click here).

HW: Ex.1.9 Q. 5 & 6

Today we revised solving simple linear equations - Section 1.8 (click here).

We then looked at Section 1.9 looking at two methods for solving simultaneous equations - The Elimination and The Substitution methods(click here).

HW: 

• Section 1.8 Q. 6 parts i and ii
  
• Section 1.9 Q.2

Today many students were absent due to choir practice so we did did not cover any new material.

We corrected the HW on patterns (click here)
We revised some questions from Section 1.5 on Identities involving long division  (click here).

Today we corrected HW from Section 1.6 - Manipulating Formula (click here).

We then introduced Algebraic Patterns Section 1.7 (click here).

HW: Sec. 1.7 Q.1
