In order to answer this we will break down the two surds into their factors. So we know that 18 is 2 multiplied by 9 and so (18)^1/2=(92)^1/2 which cane be broken down into (9)^1/2(2)^1/2 .We kno...

To solve this equation we will want to first factorise the expression into two brackets, and then see what value makes each bracket 0. transform X^2-X-12=0 into (X+c)(X+d)=0We do this by finding factor pa...

The first step to answering this question is recognising that the denominators should be factorised to find any common factors. Factorising 3/2x+12 gives 3/2(x+6) and factorising (x-15)/(x²-2x-...

first off, replace all x values with y and all y values with x, which gives us, X = 2Y + 3 / Y - 4 rearrange to give, X(Y - 4) = 2Y + 3 expand the bracket, XY - 4X = 2Y + 3 rearrange to get all Y...
