Question

f(x)=x2-25/x+25, x is not = -5​

Answer 1

Answer:

x2

Step-by-step explanation:

x2-25/x is not equal to -30

x3-25/x is not equal to -30x

X3=-5x

hence proved

Answer 2

Step-by-step explanation: x^2-25/x+25

if x≠-5 ,then the equ^n is not equal to 0,then how to find the roots

means the given equation should be equal to any fun^n or no. anything then we can find the value of x

x≠-5 ,then x+25≠20 and x^2-25≠0

then dividing the equation

x^2-25/x+25≠0/20--------        (0/20=0)

then the whole equation is not equal to 0

hence proved
