ahha nope sorry try again, note: ^ means exponent
Uhh...yeah, my answer's right. unless by 4x^2 you actually meant (4x)^2, in which case there are no real roots.
msg me ill answer it rightly, its actually a question that can be done in 2 seconds.
Uhh.. what level of math are you in? As he displayed (at minimum) lower level calculus understanding and implentation, and his answer is correct. So I don't understand how you can suggest his answer is wrong, when it's quite right given the equation provided to us.
the answer i have is based on a school textbook, maybe he is trying to figure out something wrong, or has made a mistake, the answer is 4x + 3 so someone try to explain why.
