When solving an equation with brackets, it is often easiest to expand the brackets first.3(x+1) = 21becomes...3x + 3 = 21Now this looks like an equation we know how to solve(minus three from both sides)3x...

Our ultimate goal is to figure out what m equals.The most important thing to remember is that whatever you do to the left you also do to the right.Let us start by adding 4m to both sides: 5m+4m-2=16-4m+4 ...

Firstly, (x - c) is a factor of a polynomial P(x) if and only if there exists a polynomial Q(x) such that P(x) = (x - c)Q(x), where c is a real or complex constant.
Therefore, we can write: P(x) = x...
