Question

Can I square both sides of an inequality?

A) Yes, always
B) Yes, but only for positive values
C) No, it may change the direction of the inequality
D) No, squaring is not allowed in inequalities

Answer 1

No, squaring both sides of an inequality may change the direction of the inequality.

Step-by-step explanation:

When dealing with inequalities, it is important to consider the effects of squaring both sides of the inequality. While it is possible to square both sides, it may change the direction of the inequality. This means that the new inequality may not have the same solution set as the original inequality. Therefore, the correct answer is C) No, it may change the direction of the inequality.
