Pythagoras' Theorem is a rule for right-angled triangles which is used to solve problems. Explanation: For any right-angled triangle, the longest side (opposite the right angle) is called the hypotenuse . If...

First you determine which value is a, b, or c in the polynomial. Then you insert those values into the equation correctly.

First look at the constant coefficient, which in this case is 2. You need two numbers which will multiply together to make this number. The only pairs of numbers that will make 2, are (1 and 2) or (-1 and -2...

Method First Look for a term (i.e x , y, z) which is in all the compoents Also look if there is a possible common factor that the compoents share Soloution ​x is a shared term , and 2 is a common multiple Th...

In this question I would initially aim to get an a on both sides of the equation. My first step would be to multiply both sides by (4-a) to do this. After this point I would expand out the brackets on the le...
