Question

If x^2a-3.y^2a=x^6-a.y^5a then the value of a|(x/y) is

​

Answer 1

Answer:

Step-by-step explanation:

Hi baby

a=-4/3

Method 1

x^3+ax^2-2x+a+4=(x+a)(x^2-2)+(3a+4)

as x+a is a factor therefore the constant term (i.e. 3a+4) should be zero which will give us a=-4/3

Method 2

let f(x)=x^3+ax^2-2x+a+4

and if x+a is a factor of f(x) the x=-a will be a solution to the equation f(x)=0.

On solving f(-a)=0

we get a=-4/3
