Best ResponseYou've already chosen the best response.0its basically, the answer to part of the quadratic equation which is b^2  4ac

Best ResponseYou've already chosen the best response.0i think its 0, b, b/c it only has one x intercept, am i right?

Best ResponseYou've already chosen the best response.0well, if what you said for discriminate is correct then the answer I got is 36 b^2  4ac (6) ^2  4 a(0) 6^2 = 36 4a(0) = 0 but 36 is not one of the answers, did i do something wrong?

Best ResponseYou've already chosen the best response.0the equation of the graph is \[y=(x+5)^2\] which is equivalent to y = x^2+10 x+25 hence a=1,b=10 and c=25. the discriminant is 10^2 (4)(1)(25)=0

Best ResponseYou've already chosen the best response.0Oh i see, I thought that the (B,C) above the point was supposed to be b and c to solve the equation but instead you find the actual equation and solve with that. Thanks, event though this wasn't my question.

Best ResponseYou've already chosen the best response.0Really? wow okay, i'm stupid, bad resolution on my screen made it look like b and c not 5 and 0 sorry.

Best ResponseYou've already chosen the best response.0okay, then put in the negative, (x5)^2 X^210x+25 a =1; b = 10; c = 25 b^24ac (10)^2  4 (1)(25) 100  100 = 0 same answer (by the way, when graphing exponential equations, what ever number added to x inside those () will be moved to the left on the xaxis) what Safiah said was correct but even differently its the same answer
