Solve for \( x \).

\[ x(x + 9) = 0 \]

What does \( x \) have to be for the answer to be 0?

when we solve the equation it will become x ² + 9x*= 0 now here a = 1 , b = 9 and c = 0 by using quaderatic formula x = -b +,- √ b ² - 4ac / 2a ( 2a is divided by all terms ) by putting values x = - 9 +,**- √ 81 / 2(1) ( √ 81 = 9)**
x = -9 + 9 / 2 and x = -9 -9 /2 x = 0 and x = -18 /2 = -9 now there are two values for x one is- 9 and other is 0 so we put -9 as the value of x then answer will be zero..*

x ( x + 9 ) = 0 x = 0 ∨ x = − 9

The solutions for the equation x ( x + 9 ) = 0 are x = 0 and x = − 9 . Thus, x can be 0 for the product to be zero. Either value of x satisfies the equation.
