Best ResponseYou've already chosen the best response.1correct so you will get \[\huge\rm \frac{ 7x^2 }{ 7}\frac{ 14x }{ 7}+\frac{ 7 }{ 7 }=0\]

Best ResponseYou've already chosen the best response.1after factor it ot 7(x^22x+1)=0 now set it equal to zero \[7\cancel{=}0 ~~~~x^22x+1=0\] now factor x^22x+1=0

Best ResponseYou've already chosen the best response.1nope 2 times 1 = 2 but it suppose to be one find two number when you multiply them you should get 1 and when you add or subtract them you should get 2

Best ResponseYou've already chosen the best response.1easy method to factor quadratic equation find two number when you multiply them you should get product of AC and when you add or subtract them you should get middle term a=leading coefficient b=middle term c=constant term
