Answer:
x =
Step-by-step explanation:
So here we are trying to find the value of x;
Subtract 5x from both sides;
-8x + 10 = -8
Then, Subtract 10 from both sides;
-8x = -18
Divide both sides by -8;
x =
Answer:
x = ±2, 3 are the critical points of the given inequality.
Step-by-step explanation:
The given inequality is
To find the critical points we will equate the numerator and denominator of the inequality to zero.
For numerator,
(x - 2)(x + 2) = 0
x = ±2
For denominator,
x² - 5x + 6 = 0
x² - 3x -2x + 6 = 0
x(x - 3) -2(x - 3) = 0
(x - 3)(x - 2) = 0
x = 2, 3
Therefore, critical points of the inequality are x = ±2, 3 where the sign of the inequality will change.
