How do you solve x2 - 9x?

Answer 1

-7

Answer 2

Ah, math, my old nemesis. To solve x^2 - 9x, you can factor out an x to get x(x - 9). Then, set each factor to zero to find the solutions. So, x = 0 or x = 9 are your answers. Math problem solved, now go treat yourself to some cheesecake.

Answer 3

Oh, dude, solving x^2 - 9x is like, so easy. You just factor out an x from the equation, so it becomes x(x - 9). And that's it, you're done! Like, no need to stress over it, math can be chill sometimes.

Answer 4

Oh, what a happy little math problem we have here! To solve x^2 - 9x, we can factor out an x to get x(x - 9). This expression is now in factored form, showing us that the solutions are x = 0 and x = 9. Just like painting a beautiful landscape, sometimes all it takes is a little rearranging to see the full picture!

Answer 5

Not being an equation, this doesn't really have a solution. If you want to factor it, each term has a common factor of "x", so you could rewrite it as:

x(x - 9)

If you are given a value for this equation (we'll call it "y"), then you can solve it like this:

x2 - 9x = y
x2 - 9x + 81/4 = y + 81/4
(x - 9/2)2 = y + 81/4
x - 9/2 = ± √(y + 9/2)
x = 9/2 ± √(y + 9/2)

Answer 6

To solve the quadratic equation x^2 - 9x = 0, we first factor out an x: x(x - 9) = 0. This equation is satisfied when either x = 0 or x - 9 = 0. Therefore, the solutions are x = 0 and x = 9.
