Answer 1

Answer:

5. third zero =4

6. k=-1 and2/3

Step-by-step explanation:

5. x=root 3 ___ x minus root3=0

x=-root 3 __ x+ root 3

multiply both=x^2-3

x^3-4x^2-3x+12=x^2-3×x-4+0

quotient x-4

x-4=0 x=4

6. alpha^2+beta^2= (alpha+beta)^2-2alpha×beta

24 =(-4/k)^2-2(4/k)

24k^2=16-8k

24k^2+8k-16

3k^2+k-2

3k^2+3k-2k-2 middle term split

3k(k+1)-2(k+1)

3k-2=0 k+1=0

k=2/3,-1

hope it helps
