Step 1: Find the highest common factor of the terms in the expression eg. 3x+12. In this expression 3 is the highest common factor of the terms 3x and 12...

The answer is P^7 because p is the same in both numbers and their powers need to be added up

integral of cos²(x)*sin(x) we notice that we can use the spot the ball method here: Guessed integral: cos³(x) Differentiated Guessed Integral: -3sin(x)cos²(x), therefore o...

My explanation would depend on the level of understanding of the person but one way would be the following:

We know that a = 2. Substitute the value of "a" in the given equation:

2...

We can see right off the bat that this is a quadratic equation. As always with quadratics, it is easiest to see if it factorises first. To factorise, you need to find two numbers that multiply together to...
