FAQs on Introduction: Quadratic Equations Video Lecture - Crash Course: Class 10
| 1. What is a quadratic equation? |  |
Ans. A quadratic equation is a polynomial equation of the second degree, in which the highest power of the variable is 2. It can be written in the form ax^2 + bx + c = 0, where a, b, and c are constants.
| 2. How do you solve a quadratic equation by factoring? | |
Ans. To solve a quadratic equation by factoring, follow these steps:
1. Rewrite the equation in the form ax^2 + bx + c = 0.
2. Factor the quadratic expression on the left side of the equation.
3. Set each factor equal to zero and solve the resulting linear equations.
4. Find the values of x that satisfy the original equation by substituting the solutions from step 3 back into the equation.
| 3. Can a quadratic equation have more than two solutions? | |
Ans. No, a quadratic equation can have at most two solutions. This is because a quadratic equation is of the second degree and can be represented by a parabola, which can intersect the x-axis at most twice. The solutions can be real or complex, but there will be at most two distinct solutions.
| 4. What is the quadratic formula and how is it used to solve quadratic equations? | |
Ans. The quadratic formula is used to solve quadratic equations that cannot be easily factored. It states that for a quadratic equation ax^2 + bx + c = 0, the solutions for x can be found using the formula:
x = (-b ± √(b^2 - 4ac)) / (2a)
By substituting the values of a, b, and c from the given quadratic equation into the formula, we can find the solutions for x.
| 5. What is the discriminant of a quadratic equation and how does it determine the nature of the solutions? | |
Ans. The discriminant of a quadratic equation is the expression b^2 - 4ac, which is found in the quadratic formula. It determines the nature of the solutions as follows:
1. If the discriminant is positive (b^2 - 4ac > 0), the quadratic equation has two distinct real solutions.
2. If the discriminant is zero (b^2 - 4ac = 0), the quadratic equation has one real solution (also known as a double root).
3. If the discriminant is negative (b^2 - 4ac < 0), the quadratic equation has two complex solutions (conjugate pairs) that involve the imaginary unit i.
