Question

find the remainder and tell weather 2x-1 is a factor of 2xcube -xsquare+3x-1 or not

Answer 1

Heya!

Here is yr answer.....


=> 2x³ - x² + 3x - 1

(2x-1) = 0
2x = 1
x = 1/2


=> 2(1/2)³ - (1/2)² + 3(1/2) - 1

=> 2(1/8) - (1/4) + 3/2 - 1

=> 1/4 - 1/4 + 3/2 - 1

=> 1-1+6-4/4

=> 7-5/4

=> 2/4

=> 1/2


Therefore, (2x-1) is not the zero of the polynomial!

Hope it hlpz..
