Question

The Remainder when xcube + 3x square +1 is divided by (x + ½) is ​

Answer 1

Answer:

27/8

Step-by-step explanation:

Dividend = x³+3x²+3x+1

Dividend = x³+3x²+3x+1Divisor = x - 1/2

Dividend = x³+3x²+3x+1Divisor = x - 1/2Quotient = x² + 7x/2 + 19/4

Dividend = x³+3x²+3x+1Divisor = x - 1/2Quotient = x² + 7x/2 + 19/4Remainder = 27/8

Step-by-step explanation:

Quotient :x²+7x/2+19/4

x-1/2)x³+3x²+3x+1(

***** x³ -x²/2

____________________

******** 7x²/2 +3x

******** 7x²/2 -7x/4

_________________________

************** 19x/4 +1

************** 19x/4 -19/8

___________________________

********Remainder (27/8)

Therefore,

Dividend = x³+3x²+3x+1

Divisor = x - 1/2

Quotient = x² + 7x/2 + 19/4

Remainder = 27/8

I hope u understood :D
