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.
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.
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!
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)
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.

How do you solve x2 equals 9x?
Divide both sides of the equation by x: x2 = 9x x2 / x = 9x / x x = 9
Solve for x - x2-9x plus 14 equals 0?
x - x2 - 9x + 14 = 0 ; whence, x2 + 8x = 14 , x2 + 8x + 16 = 30 , and x + 4 = ±√30 . Therefore, x = ±√30 - 4 .
How do you factor x2-9x?
x2-9x = x(x-9)
Factorise x2 minus y2 plus 9x minus 9y?
x2 - y2 + 9x - 9y =(x2 + 9x) - (y2 + 9y) =x(x + 9) - y(y + 9)================================Another way to go after it:x2 - y2 + 9x - 9y =(x2 - y2) + 9x - 9y =(x + y) (x - y) + 9 (x - y) =(x + y + 9) (x - y)
X2 - 9x - 6 equals 0?
x2 - 9x - 6 = 0 x2 - 9x + (9/2)2 = 6 + (9/2)2 (x - 9/2)2 = 6 + 81/4 x - 9/2 = ± √105 / 2 x = (9 ± √105) / 2
How do you solve x2 equals 9x?
Divide both sides of the equation by x: x2 = 9x x2 / x = 9x / x x = 9
How do you factor x2 - 9x equals -8?
x2 - 9x = -8 ∴ x2 - 9x + 8 = 0 ∴ (x - 1)(x - 8) = 0 You can then solve it as well: ∴ x ∈ {1, 8}
Solve for x - x2-9x plus 14 equals 0?
x - x2 - 9x + 14 = 0 ; whence, x2 + 8x = 14 , x2 + 8x + 16 = 30 , and x + 4 = ±√30 . Therefore, x = ±√30 - 4 .
