. Which of the following is not a quadratic equation

(a) x² + 3x – 5 = 0

(b) x² + x3 + 2 = 0

(c) 3 + x + x² = 0

(d) x² – 9 = 0

Answer/Explanation

Answer: b

Explaination:Reason: Since it has degree 3.

2. The quadratic equation has degree

(a) 0

(b) 1

(c) 2

(d) 3

Answer/Explanation

Answer: c

Explaination:Reason: A quadratic equation has degree 2.

3. The cubic equation has degree

(a) 1

(b) 2

(c) 3

(d) 4

Answer/Explanation

Answer: c

Explaination:Reason: A cubic equation has degree 3.

4. A bi-quadratic equation has degree

(a) 1

(b) 2

(c) 3

(d) 4

Answer/Explanation

Answer: d

Explaination:Reason: A bi-quadratic equation has degree 4.

5. The polynomial equation x (x + 1) + 8 = (x + 2) {x – 2) is

(a) linear equation

(b) quadratic equation

(c) cubic equation

(d) bi-quadratic equation

Answer/Explanation

Answer: a

Explaination:Reason: We have x(x + 1) + 8 = (x + 2) (x – 2)

⇒ x² + x + 8 = x² – 4

⇒ x² + x + 8- x² + 4 = 0

⇒ x + 12 = 0, which is a linear equation.
