Question

please any one tell me not wrong please its too urgent !​

Answer 1

Answer:

Step-by-step explanation:

given value of x^2+1/x^2=14

we know the formula of a^3+b^3=(a+b)(a^2+b^2-ab)

x^3+1/x^3

(x)^3+(1/x)^3 equation one

[(x)+(1/x)]^2-2=x^2+1/x^2

(x+1/x)^2-2=14

(x+1/x)^2=16

x+1/x= +4 or -4 equation 2

given x^3+(1/x)^3= (x+1/x)(x^2+(1/x)^2-x*1/x)

we kow the value of x+1/x= +4 or -4

x^2+1/x^2= 14

apply the value  +4 =  (4)(14-1)=52

apply the value -4= (-4)(14-1)=-52
