NickRBest ResponseYou've already chosen the best response.0
so (4x3)^2=(4x3)(4x3) right
 one year ago

NickRBest ResponseYou've already chosen the best response.0
so take that and foil it

HeroBest ResponseYou've already chosen the best response.0
(4x3)(4x3) = 4x(4x  3)  3(4x  3) = 16x^2  12x  12x +9 = 16x^2  24x + 9

NickRBest ResponseYou've already chosen the best response.0
but its not = to 0 its =15

HeroBest ResponseYou've already chosen the best response.0
(4x3)(4x3) = 4x(4x  3)  3(4x  3) = 16x^2  12x  12x +9 = 16x^2  24x + 9

my bad see you already did that
 one year ago

NickRBest ResponseYou've already chosen the best response.0
so now is there a common number that they are all divisible by?

KG1234Best ResponseYou've already chosen the best response.0
wait im at 16x^224x+9=15 right?
 one year ago

NickRBest ResponseYou've already chosen the best response.0
ya then add the 15 to get 16x^224x+24=0
 one year ago

NickRBest ResponseYou've already chosen the best response.0
now find a common denominator
 one year ago

KG1234Best ResponseYou've already chosen the best response.0
so does that then turn into 2x^23x=3=0?
 one year ago

HeroBest ResponseYou've already chosen the best response.0
16x^224x+9=15 16x^2  24x + 24 = 0 8(2x^2  3x + 3) = 0 2x^2  3x + 3 = 0 x^2  3/2 + 3/2 = 0 x^2  3/2x = 3/2 x^2 3/2x + 9/16 = 3/2 + 9/16 (x  3/4)^2 = 15/16 Solution is imaginary
