Question

(i) 5x + y
(ii) 2x2 - 4x² +5
(ii) x² – 2x² + 4
(v) 6x?y2 - 7xy
Write down the degree of each of the following polynomials:
(i) 3x2 - 5x + 7 (ii) 6x + 5
(iii) 6x
(vi) 5x² + 4x + 6x² (vii) 3x + y - 4x4
Add the following polynomials :
(i) 4x2 + 5x and 3x2 - 5x
(ii) 2x²y + x and 2xy
(iii) 4x2 + 2x - 3,3x3 - 2x2 - 4x + 5 and 6x2 - 7x2 - 2x + 4
(iv) 5x2 - 7xy + 4y2 - 3x, 4x2 + 2xy - y2 + y and x2 + 5xy - 2y2 + 3x -
(v) 7x2 - xy + y2 - 3x2 - 2y2 + 2xy, and - xy + y2 - 4x2
Subtract:
(i) 2x 3 - 5xy + 4y2 from 4x2 - 6xy - 9y2
() * x2 + xy + x2 + 1 y 2 from x2 + xy + x2 by
(ii) x3 – xy2 + 5x”y - y from y3 – x3 + 2xy2 – 3x²y
(iv) 1 + x + x2 - x from 2x2 – 3x3 + 4x - 7
