If you would like to solve the equation x^2 + 9x - 22 = 0, you can do this using the following steps:
x^2 + 9x - 22 = 0
(x - 2) * (x + 11) = 0
1. x = 2
2. x = - 11
The correct result would be x = 2 and x = - 11.
x^2 + 9x - 22 = 0
(x - 2) * (x + 11) = 0
1. x = 2
2. x = - 11
The correct result would be x = 2 and x = - 11.
Answer:
x = 2 , - 11.
Step-by-step explanation:
Given : x² + 9x – 22 = 0
To find : What values of x make the equation.
Solution : we have given x² + 9x – 22 = 0
On factoring
x² + 11x - 2x – 22 = 0 .
Taking common x from first two term and -2 from last two terms.
x ( x +11) - 2 (x +11) = 0.
On grouping
(x -2) (x +11) = 0
For
x - 2 =0
x = 2 .
For
x + 11 = 0
x = -11.
Therefore, x = 2 , - 11.
