Question

optain all the zeroes of 3x4 + 6x3 - 2x2 -10x - 5 if zero ar

Answer 1

Step-by-step explanation:

3*4 + 6×3- 2×2 -10x -5

= 12+18-4_10x-5

= 30-9-10x

=31-10x

so x=10/31

Answer 2

Step-by-step explanation:

Step :- 1

Given ,

p(x) = 2x^4 - 3x^3 -3x^2 +6x-22x

4

−3x

3

−3x

2

+6x−2

1 and \frac{1}{2}

2

1

are its two zeroes

(x-1) and\ ( 2x - 1 )(x−1)and (2x−1) is a factor

2x^2 - x - 2x + 12x

2

−x−2x+1

2x^2 - 3x + 12x

2

−3x+1

Step :- 2

Step :- 3

x^2 - 2x

2

−2 is also a factor

x^2 - (\sqrt{2})^2x

2

−(

2

)

2

(x - \sqrt{2} ) (x + \sqrt{2} )(x−

2

)(x+

2

)

Other zeroes are \sqrt{2}

2

and -\sqrt{2}−
