corecct answer will be marked as braniliest

Answer 1

3x+8=0

Step-by-step explanation:

3x=0-8

3x=-8

x=8/3

Answer 2

Answer:

By splitting the middle term:--

x²-4x-2x+8=0

x(x-4) -2(x-4)

(x-4)(x-2)

$\alpha = 4 \: and \: \beta = 2$

Now,Sum of squares of roots:-

${ \alpha }^{2} + { \beta }^{2}$

${4}^{2} + {2}^{2}$

$16 + 4$
