standard form of x²=9​

Sagot :

Answer:

The standard form of a quadratic equation is ax² + bx + c = 0. To get the standard form of x² = 9, we need to move the 9 to the left side of the equation:

x² - 9 = 0

Therefore, the standard form of x² = 9 is

x² - 9 = 0.

The only action you can take is to transpose 9 to the other side which makes it x² - 9 = 0. Thus, the answer being

x² - 9 = 0
