Question

if x=c is root of order 2 of polynomial f(x) then x=c is also a root of polynomial of
a) f'(x)
b) f''(x)
c)f'"(x)

plss explain a bit
give reason plss​

Answer 1

From the given information, we have

f(x)=(x−c)g(x)

where g(x) is a polynomial of degree n−m

Then x=c is a common root for equation

f(x)=0 ;f¹(x) =0; f²(x)=o......

similiarily

${f}^{m - 1}(x) = 0$

hope it helps

Answer 2

for this sum we have to plus the digits
