Question

find all the zeros of 2 x 4 - 3 x cube minus 3 X square + 6 x minus 2 if​

Answer 1

Answer:

oooommmmggggg follow me

Answer 2

Answer:

1,0.5,+√2,-√2

Step-by-step explanation:

on putting x=1

the entire thing becomes 0

therefore,(x-1) is a factor

on dividing using long division method

we get

          ____________________

     x-1)2x^4-3x^3-3x^2+6x-2       (2x^3-x^2-4x+2

         -(2x^4-2x^3)

                   -x^3-3x^2+6x-2

                   -(x^3+x^2)

                           -4x^2+6x-2

                          -(-4x^2+4x)

                                        2x-2

                                        -(2x-2)

                                            00

therefore,we get 2x^3-x^2-4x+2

   x^2(2x-1)-2(2x-1)=(2x-1)(x^2-)

therefore we will get zeroes at

1,0.5,+√2,-√2
