Question

the term of the polynomial x³-4x²-3x+2

Answer 1

Answer:

x3-4x2-3x+2

degree of polynomial = 3+2=5

so degree of polynomial is 5

Answer 2

Answer:

Given,

f( x ) = px³ + 4x² + 3x - 4

g( x ) = x³ - 4 + p

r( x ) = ( x - 3 )

Now,

=> ( x - 3 ) = 0

=> x = 3

So, 3 is a zero of r( x ).

By Remainder Theorem,

=> f( x ) = px³ + 4x² + 3x - 4

By substituting x = 3.

=> f( 3 ) = p( 3 )³ + 4( 3 )²+ 3 × 3 - 4

=> f( 3 ) = p( 27 ) + 4( 9 ) + 9 - 4

=> f( 3 ) = 27p + 36 + 9 - 4

=> f( 3 ) = 27p + 45 - 4

=> f( 3 ) = 27p + 41 ------- ( 1 )

Now,

=> g( x ) = x³ - 4 + p

By substituting x = 3 ,

=> g( x ) = 3³ - 4 + p

=> g( x ) = 27 - 4 + p

=> g( x ) = 23 + p ------- ( 2 )

According to question ,

Remainders are equal.

So,

=> 23 + p = 27p + 41

=> 23 - 41 = 27p - p

=> -18 = 26p

=> p = ( -18 / 26 )

=> p = -9/13.

Hence, p = ( -9/13 ).
