x - 1

x - 2

x + 2

​

Answer 1

$\huge\star\mathfrak\red{{Hey Mate...!!}}$

● If x-1=0 is a factor of the given polynomial then by putting x= 1 Will fully satisfy the equation.

So

$=> 2{x}^3 - 4{x}^2 + 5x -3$

$=> 2{(1)}^3 - 4{(1)}^2 + 5(1) - 3$

$=> 2(1) - 4(1) + 5 - 3$

$=> 2 - 4 + 5 - 3$

$=> 7 - 7$

$=> 0$

Answer 2

Answer:

● If x-1=0 is a factor of the given polynomial then by putting x= 1 Will fully satisfy the equation.

So

=> 2{x}^3 - 4{x}^2 + 5x -3=>2x

3

−4x

2

+5x−3

=> 2{(1)}^3 - 4{(1)}^2 + 5(1) - 3=>2(1)

3

−4(1)

2

+5(1)−3

=> 2(1) - 4(1) + 5 - 3=>2(1)−4(1)+5−3

=> 2 - 4 + 5 - 3=>2−4+5−3

=> 7 - 7=>7−7

=> 0=>0
