Didn't skip level... but his Math very advance liao so I'm finding it hard to help him when he has questions. His math tuition teacher has to keep challenging him with harder questions because he find those at school too easy.

Anyway, he solved that question I posted earlier by himself before I gave him the answer from one of the bro here.

Your son is very advance in math. Can put him for math olympiad and get medals.

Yes, the answer is 2. Just base on top two equations, 30-28=2 base on police car in both equation :)

13+13=28

17+13=30

15+17=32

17-15=2

Could the answer be 720 as a result of 2 to the power of 4 multiplied by 3,3 and 5 (16x9x5 to be exact)?

How to solve for x in this equation?

 

2x^4 + 4x^3 + 6x^2 + 4x + 2 = 0

 

I figured out that it can probably only be factorised into 2 quadratic equations, both of which do not have real roots?
