Classify the following polynomials as linear, quadratic, cubic and biquadratic polynomials:
(i) x+x2+7y2 (ii) 3x-2
(iii) 2x+x2
(iv) 3y (v) t2+1
(vi) 7t4+4t3+3t-2
Given polynomial,
(i) x+x2+7y2 is quadratic as degree of polynomial is 2.
(ii) 3x-2 is linear as degree of polynomial is 1.
(iii) 2x+x2 is quadratic as degree of polynomial is 2.
(iv) 3y is linear as degree of polynomial is 1.
(v) t2+1 is quadratic as degree of polynomial is 2.
(vi) 7t4+4t3+3t-2 is bi-quadratic as degree of polynomial is 4.
