If you have a claim which says something about every element in a list of elements with each element depending on previous elements, induction might be a useful starting point. In your exams, that "l...
We can start by recognising one of our properties of log. That is loga(x) - loga(y) = loga(x/y). Performing this on our question we get: log3((3b+1)/(a-2)) = -1...
To start, let us recall the form of a quadratic equation. y = ax2 + bx + c. When making x the subject of the formula and setting y = 0, we get the quadratic formula, as you may have seen before...
The answer is of the form ax2+bx+c The a term is found by the product of the coefficients of the x in the brackets. e.g (2x+7)(-4x+6) would give -8STAnswered by Sam T. • Maths tutor5193 Views
