Two 45cm lengths cut off 240cm long wire. 240 - (2*45) = 150cmHow many 40cm length wires can be cut out of the remainder 150cm wire?150/40= 3.75As we are looking for entire 40cm length wires, we disregard...

There are no real answers for this equation.This is because you would have to square root a negative number to solve the equation and that is a mathmatic impossibility.

I would explain on the whiteboard how to factorise itleading them to having two brackets, (x + 3) and (x+3). Could also be written as (x+3)^2then teach them on whiteboard how to solve the equation(x+3)^2 ...

2cos(2x)

Thinking about each term individually, we can rewrite the equation as:3 x a x 4 x a x b = then we can multiply the numbers: 3 x 4 = 12then multiply the letters: a x a = a2 (a squared) x bnow join everythi...
