The Pythagoras Theorem only works with right-angled triangles. If you see a triangle other than right-angled triangles, then you do not need to apply the Pythagoras Theorem. The right-angled triangle h...

There are loads of different ways to solve quadratics, and most of the time there isn't only one right way to solve them.

there's three main ways that you can use to solve quadratics: fac...

first substitute all the values you know into the formula (use brackets to make your work clear)

4(4) + 2(3)

we know that 2 numbers next to eachother means multiply so expan...

If presented with an 'AND' statement, multiply the probabilites of each individual event happening by one another,If rolling a die, what is the probability of landing a 1 AND then a 21/6 * 1/6 therefore p...

Start by factoring out the common term, so in this case a.

a(q - c) = d

Now divide by a on both sides to isolate the (q - c)

(q - c) = d/a

Now ad...
