Question

Ex 2.3 class 10 maths ques no 3

Answer 1

Answer:

Step-by-step explanation:

Q - obtain all other zeros of 3x^4+6x^3-2x^2-10x-5 if its two of its zeros√5/3 and -√5/3

p(x)=3x^4+6x^3-2x^2-10x-5

x=√5/3 , x=-√5/3

x-√5/3 =0 , x+√5/3=0

(x-√5/3)(x+√5/3)=0

x^2-(√5/3)^2

x^2-5/3=0

3x^2-5 =0

g(x)=3x^2-5

now refer to the attachment

hence all zeros are √5/3 ,-√5/3,-1,-1
