Answer 1

Hey!!!

As promised I'm here to solve your question

But again I'll solve on paper for best understanding

=> k = 10

Hope this helps

Answer 2

Hello ☺

Let one zero of this polynomial is y
then another zero must be y³ A/Q

And here given

$\alpha \times \beta = 16 - - - 1)$
(given )

so, y ×y³ = 16

y⁴ = 16

y = 2

•°•$\alpha + \beta = k$

And y³ = 2³ = 8

And , y + y³ = k

Hence , 2 + 8 = k

10 = k

k= 10 Answer
