How do you factorise x(squared)+6x=1?


I'll give you a solution in a few minutes - just so you know how to do this from now on, as this question is a little trickier than normal factorisation.

Just apply the quadratic formula, find the solutions, and express the factorised form as (xa)(xb)=0(x-a)(x-b)=0 where a,ba,b are the two solutions.

No problem, nearly finished writing it out! :smile:

Just subtract 1 to make it = 0, then you've got it in the typical quadratic format. From that point, you can use brackets in the normal fashion to factorise.

Please don't post full solutions. Let OP have a go themselves first with a hint.

the roots of this equation r rational numbers I think so we were to factorise this will will have to write it in form of (x - a)(x - b) where a and b will be exact answers jn surf form. will this be correct?
