Question

( 5/9 х - 1 ) . ( х + 4) = 0

Answer 1

5/9x - 1 = 0
5/9x = 1
x = 9/5

x + 4 = 0
x = -4

x = 9/5, x = -4.

Answer 2

To solve the equation (5/9 * x - 1) * (x + 4) = 0, we can apply the zero product property, which states that if a product of factors is equal to zero, then at least one of the factors must be zero. So we can set each factor equal to zero and solve for x.

Setting (5/9 * x - 1) = 0: 5/9 * x - 1 = 0 5/9 * x = 1 x = 9/5

Setting (x + 4) = 0: x + 4 = 0 x = -4

Therefore, the solutions to the equation (5/9 * x - 1) * (x + 4) = 0 are x = 9/5 and x = -4.
