Answer 2

I did -14=-16x^2

then 14/16=x^2

then square root of 14/16

Answer 3

it is incorrect simply cos you haven't worked it out properly

you have missed out an x

Answer 4

ooh.

Answer 5

how do I solve it?

Answer 6

is it sort of like the problems I did before?

Answer 7

put the x into your equation

then divide both sides by x

Answer 8

^no, don't do that...

Just use factoring on the original problem.
\[\large 0 = -16x^2 +14x \]factor out a common factor of -2x

Answer 9

wait so do I write something on the left of the =?

Answer 10

If you do as I say the answer will be immediately apparent:

I did -14x=-16x^2

divide by -16x

Answer 11

@MrNood I don't think you should recommend that method. I used to do it before wising up.

@agent0smith
your method is exactly the same

Answer 13
