Question

step by step explanation please​

Answer 1

Answer:

X-2=0

x=2

put x=2 in p(x)

x³+3x²-ax+3=0

2³+3*2²-a2+3=0

8+12-a2+3=0

23-a2=0

-a2=-23

a2=23

a=23/2

HOPE IT HELPS...

BYE MATE..:)))))

Answer 2

Answer:

Given polynomial x³ +3x² -ax +3

x - 2 = 0

x = 2

putting x = 2 in given polynomial

(2)³+3(2)²-a(2) +3 = 0

8 + 12 -2a +3 =0

23 -2a=0

-2a = -23

a = 23/2

therefore,option (d) is the right answer.
