Answer:
(i) 8x2y3 by -2xy
Solution:
(i) 8x2y3/-2xy
= (8/-2) x2 - 1y3 - 1 [Using quotient law xm ÷ xn = xm - n]
= -4xy2.
(ii) 35x3yz2 by -7xyz
Solution:
35x3yz2 by -7xyz
= (35/-7) x3 - 1y1 - 1z2 - 1 [Using quotient law xm ÷ xn = xm - n]
= -5 x2y0z1 [y0 = 1]
= -5x2z.
(iii) -15x3yz3 by -5xyz2
Solution:
-15x3yz3 by -5xyz2.
= (-15/-5) x3 - 1y1 - 1z3 - 2. [Using quotient law xm ÷ xn = xm - n].
= 3 x2y0z1 [y0 = 1].
= 3x2z.
II. Division of a Polynomial by a Monomial
Rule:
For dividing a polynomial by a monomial, divide each term of the polynomial by the monomial. We divide each term of the polynomial by the monomial and then simplify.
Divide:
(i) 6x5 + 18x4 - 3x2 by 3x2
Solution:
6x5 + 18x4 - 3x2 by 3x2
= (6x5 + 18x4 - 3x2) ÷ 3x2 6x5/3x2 + 18x4/3x2 - 3x2/3x2
=2x3 + 6x2 - 1.
(ii) 20x3y + 12x2y2 - 10xy by 2xy
Solution:
20x3y + 12x2y2 - 10xy by 2xy
= (20x3y + 12x2y2 - 10xy) ÷ 2xy
= 20x3y/2xy + 12x2y2/2xy - 10xy/2xy
= 10x2 + 6xy
