[S1 Maths + Science PMCians]
What we did in 2 hours:
This week we started the lesson with solving quadratic equations (ie, x to the power of 2 functions).
Step 1: Shift all the terms to one side (…. = 0)
Step 2: Factorise the function
Step 3: Equate each bracket to zero and solve
We could have up to 2 solutions for such equations. As we only have 2 hours on it, we used a cheat method using our calculator to tackle the factorisation portion. In 2021, when we revisit this portion, we will explore further on how the calculator does the “guess and check”.
Solving equations are also more fun if we are expected to come up with the equation! So, we also did some word problems. Things to note when forming equation:
1) What is the key information
2) Units on both sides of the equation must be the same
Needless to say, we had fun with Kahoot! as we end off our headstart on Algebra.

See you in class! 😀
