Write a quadratic equation ax²+ bx + C = 0, whose coefficients are a =-9, b = 0, c = -2

Please I really need your help for this ​

ax² + bx + c = 0

Let's write -9 where we see A:

-9x² + bx + c = 0

Let's write 0 where we see B:

-9x² + 0.x + c = 0

(Since B = 0, when it is multiplied by x, it becomes 0 again)

-9x² + c = 0

Let's write -2 where we see C:

-9x² + -2 = 0

Now we can move on to solving our equation:)

Let's put the known and the unknown on different sides:

(-2 goes to the opposite side positively)

-9x² = 2

(it goes as a division because it is in the case of multiplying -9 across)

x² = 2/-9

I could not find the rest of it, but I did not want to delete it for trying very hard. Sorry. It felt like we should take the square root, but I couldn't find it, maybe this can help you a little bit.

Please do not report:(

I hope I got it right, I'm trying to improve my English a little :)
