Question

Solve the inequality X^2+9x<0

Answer 1

Answer:

x > -9

See the second scenario if incorrect.

Step-by-step explanation:

1...x^(2) + 9x < 0

first factor

2...x * ( x + 9 ) < 0

now divide by x

note: 0 divided by any number is 0

2... x * ( x + 9 ) < 0

    /x               /x

3... x + 9 < 0

now subtract 9

3... x + 9 < 0

        -9     -9

4... x< -9

Second scenario

In the event that x is a negative number

2... x * ( x + 9 ) < 0

dividing by x will flip the inequality sign

(3)... x + 9 > 0

subtract 9

(3)... x + 9 > 0

     -9        -9

(4)... x> -9
