Today we looked at quadratics, in particular how to:

• Factorise a quadratic expression
• Solve a quadratic equation by factorising
• Solve a quadratic equation using the quadratic formula

HW 

• Complete questions on two printed pages relating to facto rising and solving quadratics.
• Log on to Khan Academy, complete the 3 sets of questions below, and try gain 1000 points.

Use the links here and try the questions. The aim is to master each topic by getting 5 in a row correct.

KA Solve Quadratic With Factors 1

KA Solve Quadratic with Factors 2

KA Solve Quadratic with formula

Factorise the quadratic expressions below

Solve the quadratic equations below using both (i) facto rising method and (ii) formula method.

Next week I think that it would be worthwhile to look at the other 3 factorising methods on the course. Have a look at the video below to prepare.
