Can someone please explain this to me?

I'm not quite sure where the '6x' came from since when squaring the x and the 9, I would never understand where the #x came from though I know it's to get a quadratic. Can someone please explain how to solve similar sums and get the answer? Thank you!

write it out as (x+3)(x+3) then do x(x+3) + 3(x+3) to get your answer. ie multiply the second bracket by the first and second term in the first bracket seperatly

THIS IS THE DIFFERENCE OF 2 SQUARES. Step one = square the first (x squared) Step TWO= Square the second term giving you 6 Step Three = Multiple it by the first term (6x) Finally Square the last term giving you 9.

Thank you so much Jamie, I completely forgot it was cross multiplication! You see, my teacher tends to skip past steps in algebra if they're self-explanatory so I must've been absent when she was explaining it. You just saved my a*s lmaoo tysm!
