Best ResponseYou've already chosen the best response.0A good start is subtracting 64 from both sides.\[ \color{Black}{\Rightarrow 9x^2 + 3x + 25  64 = 0}\] Simplify, and solve the quadratic equation.

Best ResponseYou've already chosen the best response.29x2+30x+25=64 9x2+30x+2564 = 0 9x2+30x39 = 0 9x2 9x + 39x 39 = 0 9x(x1) +39 (x1) = 0 (9x +39) (x1) = 0 so, x = 39/9 and x =1....

Best ResponseYou've already chosen the best response.1Actually no... The solutions for x as an answer does not involve imaginary #'s, and it's not 59/3

Best ResponseYou've already chosen the best response.0The answer in the back of the book is \[x=(10+2i \sqrt14)/6, (102i \sqrt14)/6 \] I just can't figure out how it got there.

Best ResponseYou've already chosen the best response.1That answer is crazy, this has solvable real number values. Yes you can combine those to get X, but why?

Best ResponseYou've already chosen the best response.1In this case I'd say either the problem was written down for us incorrectly/incompletedirections, or the book is making it a whole lot harder than it needs be...

Best ResponseYou've already chosen the best response.1:S Go with what @Ganpat said, unless there's something missing or incorrect here with regards to the question and it's directions as you wrote it here. He's 100% correct.
