Answer 1

Step-by-step explanation:

Hola !

If ke = +6

we know that,

X+3

then,

sum of that will equal to +6.

Thank you ¡

Answer 2

$\huge\underline{\overline{\mid{\bold{\pink{ANSWER-}}\mid}}}$

p(X)=p(-3)

therefore X=-3

x+3=0 ( you told me)

let put the Value of X=-3

X²+kx-2 = -3×-3+k×-3-2

9-3k-2

7-3k

-7=-3k

7=3k

k=7/3
