Best ResponseYou've already chosen the best response.1I realized that we were missing the middle term Usually the equation is in the form \(ax^2+bx+c\) In this case the equation was in this form \(ax^2+c\) it was missing the bx So that means its difference of squares meaning that middle term canceled out

Best ResponseYou've already chosen the best response.1So anyways it is in the form \(a^2b^2=(ab)(a+b)\) \(81x^2100=(9x10)(9x+10)\) In this case our a=9x and b=10 So \(a^2=(9x)^2=81x^2 \text{ and } b^2=(10)^2=100\)
