Question

divide the following in a long division method
1) 6x^2 - 31x +40 by 2x - 5
2) x^2 +12x +35 by x+7
3) 15x^3 - 38 x^2 - 23x +6 by 3x +2
4) 2a^3- 7 a^2 - 68a -32 by a+4
5)3x^3+ 4x^2 - 109x+ 70nby x+7
whoever answers it colrrect i will mark it the brainy

Answer 1

Answer:

Let, p(x)=6x

2

−31x+47,

g(x)=2x−5

q(x)=3x−8 and r=7

∴ By division algorithm,

p(x)=g(x)×q(x)+r

=(2x−5)(3x−8)+7

=6x

2

−15x−16x+40+7

=6x

2

−31x+47

=p(x)
