FAQs on Inequalities: Algebra- 1 Video Lecture - Crash Course for CAT
| 1. What are inequalities in algebra? |  |
Ans. Inequalities in algebra are mathematical expressions that compare two quantities using inequality symbols such as < (less than), > (greater than), ≤ (less than or equal to), or ≥ (greater than or equal to).
| 2. How do you solve inequalities algebraically? | |
Ans. To solve inequalities algebraically, you can perform operations such as addition, subtraction, multiplication, and division on both sides of the inequality while following the rules for inequalities. The solution will be a range of values that satisfy the given inequality.
| 3. What is the difference between solving equations and solving inequalities in algebra? | |
Ans. When solving equations in algebra, you are finding the value of the variable that makes the equation true. In contrast, when solving inequalities, you are determining a range of values for the variable that satisfy the inequality.
| 4. How can inequalities be represented graphically on a number line? | |
Ans. Inequalities can be represented graphically on a number line by plotting points that satisfy the inequality and shading the region that includes all such points. The direction of the shading depends on the type of inequality (e.g., < or >).
| 5. What are some common mistakes to avoid when solving inequalities in algebra? | |
Ans. Some common mistakes to avoid when solving inequalities include forgetting to reverse the inequality sign when multiplying or dividing by a negative number, incorrectly applying rules for inequalities, and not considering both sides of the inequality when performing operations.
