Answer 1

Answer:

x+5=0

x=-5

Now, x^6+6x^4+4x+k=0

putting x=-5 we get

=(-5)^6+6*(-5)^4+4*(-5)+k=0

=15625+3750-20+k=0

=19355+k=0

k= -19355 Answer

Answer 2

Answer:

x+5=0

x=-5

Now, x^6+6x^4+4x+k=0

putting x=-5 we get

=(-5)^6+6*(-5)^4+4*(-5)+k=0

=15625+3750-20+k=0

=19355+k=0

k= -19355 Answer

Good morning ❤️
