Question

Divide 3ײ-׳-3×+5 by ×-1-ײand verifing that divison algorithms​

Answer 1

$\: \huge{\underline{\mathfrak\red{❥answer❣}}}$

3x²-x²-3x+5

also, -x³+3x²-3x+5

x²+x-1)-x³+3x²-3x+5 (-x+4

- x³ - x²+x

4x²-4x+5

__________

4x² - 4x-4

_________

-8x+9

clearly, remainder = -8+9

quotient = -x+4

using division algorithm,

a = b×q+r

= (x²+x-1)(-x+4)-8+9

= -x³+3x²-3x+5

also, 3x²-x³-3x+5 ( dividend)
