Answers
Answer:
the question is wrong
Step-by-step explanation:
Step-by-step explanation:
(i) A binomial of degree 35 can be: 3x35 – 4
(ii) A monomial of degree 100 can be:
4. Write the degree of each of the following polynomials:
(i) 5x3 + 4x2 + 7x (ii) 4 - y2 (iii) (iv) 3
Ans. (i) 5x3 + 4x2 + 7x
∵ The highest exponent of x is 3.
∴ The degree of the polynomial is 3.
(ii) 4 – y2
∵ The highest exponent of y is 2.
∴ The degree of the polynomial is 2.
(iii)
∵ The highest exponent of t is 1.
∴ The degree of the polynomial is 1.
(iv) 3
since, 3 = 3x°
∴ The degree of the polynomial 3 is 0.
5. Classify the following as linear, quadratic and cubic polynomials:
(i) x2 + x
(ii) x – x3
(iii) y + y2 + 4
(iv) 1 + x
(v) 3t
(vi) r2
(vii) 7x3
Ans. (i) x2 +x
∵ The degree of x2 + x is 2.
∴ It is a quadratic polynomial.
(ii) x – x3
∵ The degree of x – x3 is 3.
∴ It is a cubic polynomial.
(iii) y + y2 + 4
∵ The degree of y + y2 + 4 is 2.
∴ It is a quadratic polynomial.
(iv) 1 + x
∵ The degree of 1 + x is 1.
∴ It is a linear polynomial.
(v) 3t
∵ The degree of 3t is 1.
∴ It is a linear polynomial.
(vi) r2
∵ The degree of r2 is 2.
∴ It is a quadratic polynomial.
(vii) 7x3
∵ The degree of 7x3 is 3.
