Ex 2.1, 5 Classify the following as linear, quadratic and cubic polynomials: (i) 𝑥2+𝑥 𝑥2+𝑥 = 𝑥2+ 𝑥1 Highest power is 2 Hence, degree is 2 Hence, quadratic. Ex 2.1, 5 Classify the following as linear, quadratic and cubic polynomials: (ii) 𝑥− 𝑥3 𝑥− 𝑥3 = −𝑥3 + 𝑥﷮1﷯ Highest power is 3 Hence, degree is 3 Hence, cubic. Ex 2.1, 5 Classify the following as linear, quadratic and cubic polynomials: (iii) 𝑦﷮2﷯+𝑦+4 𝑦﷮2﷯+𝑦+4 = 𝑦﷮2﷯+ 𝑦﷮1﷯+ 4𝑥𝑦﷮0﷯ Highest power is 2 Hence, degree is 2 Hence, quadratic. Ex 2.1, 5 Classify the following as linear, quadratic and cubic polynomials: (iv) 1+𝑥 1 + 𝑥 = 𝑥﷮1﷯+ 1𝑥𝑥﷮0﷯ Highest power is 1 Hence, degree is 1 Hence, linear. Ex 2.1, 5 Classify the following as linear, quadratic and cubic polynomials: (v) 3𝑡 3t = 3 × 𝑡﷮1﷯ Highest power is 1 Hence, degree is 1 Hence, linear. Ex 2.1, 5 Classify the following as linear, quadratic and cubic polynomials: (vi) 𝑟﷮2﷯ 𝑟﷮2﷯ = 𝑟﷮2﷯ Highest power is 2 Hence, degree is 2 Hence, quadratic. Ex 2.1, 5 Classify the following as linear, quadratic and cubic polynomials: (vii) 𝑟﷮2﷯ 7𝑥﷮2﷯ = 7×𝑥﷮3﷯ Highest power is 3 Hence, degree is 3 Hence, cubic.
