(x+2)(x+3)=x(x+3)+2(x+3)(x+2) (x+3)=x(x+3)+2(x+3) Can you simplify that?

The thread has been moved to Maths since it is maths-related.

I like to call this the 'Smiley face method'.
Multiply the lines out - so whichever value the coloured line starts at, multiply it by the value it ends at. These lines will in the same position for any two brackets that are next to each other.
Once you've multiplied each coloured line, add the products together and this will form a quadratic.

Would you like to give it a shot and show me what you get? :smile:
