Best ResponseYou've already chosen the best response.1your equation is 7x^26x = 2 we need to add 2 to both sides first, to get 0 on the right side 7x^2  6x + 2 = 0 giving us: a = 7, b = 6, c = 2 (not 2)

Best ResponseYou've already chosen the best response.1anyway, after we plug in a, b, and c we get: dw:1440032970739:dw

Best ResponseYou've already chosen the best response.1dw:1440033237890:dw now, if you haven't learned about imaginary numbers, we would put "no solution" as our answer since the square root of 20 is an imaginary number. otherwise, we can keep going

Best ResponseYou've already chosen the best response.1then divide everything by 2, giving us: dw:1440033419750:dw which ends up being our answer, if we are considering imaginary numbers
