The expression "x subtract 9" can be written as x - 9. This means you are taking the value of x and subtracting 9 from it. For example, if x = 15, then x - 9 would be 15 - 9 = 6. Therefore, the result of x subtract 9 depends on the value of x.

Unless you have a value for x, it cannot be simplified any further so it will be:
x - 9

Just X to the second power minus nine. You can't subtract nine from x to the second power unless you know what x is.

sorry i am not sure but i dont think it has an answer If this equation is: x^2 - 36 = 5x, then: x^2 - 36 = 5x subtract 5x to both sides; x^2 - 5x - 36 = 0 Factor; (x + 4)(x - 9) = 0 x + 4 = 0 or x - 9 = 0 x = -4 or x = 9
x=3 y=9 7x + 4y =? (7 * 3) + (4 * 9) = 57 Remember always multiply/divide before you add/subtract
