Question

the sum of the zeros of polynomial 3x square-2x -8 is ​

Answer 1

Answer:3x sq-2x-8=0

3x sq -6x +4x -8=0

3x( x-2) +2(x-2)=0

(x-2)(3x+2)=0

x=2,-2/3

sum of zeros =2+(-2/3)=2-2/3

=4/3

Step-by-step explanation:

Answer 2

Answer:

The correct answer to this question is 2 and -4/3.

Step-by-step explanation:

3x²-2x-8

3x²-2x-8By splitting the middle term,we have

3x²-2x-8By splitting the middle term,we have3x²-6x+4x-8

3x²-2x-8By splitting the middle term,we have3x²-6x+4x-83x(x-2)+4(x-2)

3x²-2x-8By splitting the middle term,we have3x²-6x+4x-83x(x-2)+4(x-2)(3x+4)(x-2)

3x²-2x-8By splitting the middle term,we have3x²-6x+4x-83x(x-2)+4(x-2)(3x+4)(x-2)For Zeros=> 3x+4=0

3x²-2x-8By splitting the middle term,we have3x²-6x+4x-83x(x-2)+4(x-2)(3x+4)(x-2)For Zeros=> 3x+4=0 3x=-4

3x²-2x-8By splitting the middle term,we have3x²-6x+4x-83x(x-2)+4(x-2)(3x+4)(x-2)For Zeros=> 3x+4=0 3x=-4 x=-4/3

3x²-2x-8By splitting the middle term,we have3x²-6x+4x-83x(x-2)+4(x-2)(3x+4)(x-2)For Zeros=> 3x+4=0 3x=-4 x=-4/3x-2=0

3x²-2x-8By splitting the middle term,we have3x²-6x+4x-83x(x-2)+4(x-2)(3x+4)(x-2)For Zeros=> 3x+4=0 3x=-4 x=-4/3x-2=0x=2

3x²-2x-8By splitting the middle term,we have3x²-6x+4x-83x(x-2)+4(x-2)(3x+4)(x-2)For Zeros=> 3x+4=0 3x=-4 x=-4/3x-2=0x=2The zeros are -4/3 and 2.

3x²-2x-8By splitting the middle term,we have3x²-6x+4x-83x(x-2)+4(x-2)(3x+4)(x-2)For Zeros=> 3x+4=0 3x=-4 x=-4/3x-2=0x=2The zeros are -4/3 and 2.SUM OF ZEROS= -b/a

3x²-2x-8By splitting the middle term,we have3x²-6x+4x-83x(x-2)+4(x-2)(3x+4)(x-2)For Zeros=> 3x+4=0 3x=-4 x=-4/3x-2=0x=2The zeros are -4/3 and 2.SUM OF ZEROS= -b/a = -(-2)/3

3x²-2x-8By splitting the middle term,we have3x²-6x+4x-83x(x-2)+4(x-2)(3x+4)(x-2)For Zeros=> 3x+4=0 3x=-4 x=-4/3x-2=0x=2The zeros are -4/3 and 2.SUM OF ZEROS= -b/a = -(-2)/3 = 2/3
