Answer 9

solve for x... to do that you must get it alone. To do that you need to separate x from the equation to eliminate x^2 and from the 9.

Answer 10

its okay i moved on from that question

Answer 11

so it becomes x(x+9) = 0 .. then from there set both values of = to 0, so that way ie. x+9 = 0.... you can move 9 to the other side (subtract it) and what do you get? X all by its self...
which gives you 0 and -9 as the values of x.....
