Answer 2

Question :-

Divide !

1. (x⁴+x³-3x²+3x-12) ÷ (2+x²)
2. (a⁴-a³+a²-a+1) ÷ (a³ - 2)
3. (4x⁴-5x³-7x+1) ÷ (4x-1)

ANSWER

Solution : -

1.

(x⁴+x³-3x²+3x-12) ÷ (2+x²)

2+x² )x⁴+x³-3x²+3x-12(

This can be written as;

x²+2 )x⁴+x³-3x²+3x-12(x²+x

x⁴ +2x²

(-) (-)

0+x³-5x²+3x

x³ +2x

(-) (-)

0-5x²+x

2.

(a⁴-a³+a²-a+1) ÷ (a³ - 2)

a³-2 )a⁴- a³+a²-a+1(a³+1

a⁴-2a³

(-) (+)

0+ a³+a²-a+1

a³ -2

(-) (+)

a²-a+3

3.

(4x⁴-5x³-7x+1) ÷ (4x-1)

4x-1 )4x⁴-5x³+0-7x+1(x³-x²-(x)/(4)-(29)/(16)

4x⁴-x³

(-) (+)

-4x³+0

-4x³+x²

(+) (-)

- x²-7x

-x² +(x)/(4)

(+) (-)

(-29x)/(4) + 1

(-29x)/(4) + (29)/(16)

(-) (-)

(-13)/(16)
