Answer 1

Answer:

1st one is d, 2nd one is c, 3rd one is c, 4th one is b

Step-by-step explanation:

3x²+ax-14=0

3(2)²+a(2)-14=0

3(4)+2a-14=0

12+2a-14=0

2a-2=0

2a=2

a=1

2x³+bx²+x-2=0

2(2)³+b(2)²+2-2=0

2(8)+b(4)=0

16+4b=0

4b=-16

b= -4

a-2b = 1-2(-4)

= 1+8

= 9

p(x) = k[x²-(alpha + beta)x+ alpha×beta]

= k[x²-(1/4)x+(-1)]

= k[x²-1/4x-1]

where k=4

=4x²-x-4

hope this helps you
