Question

If (x -a) is a factor of
X8 - ax7 + x6 -
ax5 + x4 - ax3 + 3x -a + 2 = 0​

Answer 1

Answer:

a = -1

Step-by-step explanation:

Since, x - a = 0

So, x = a

Therefore, a8 - a*a7 + a6 - a*a5 + a4 - a*a3 + 3a - a + 2 = 0

=> a8 - a8 + a6 - a6 + a4 - a4 + 2a + 2 = 0

=> 2a + 2 = 0

=> 2a = -2

=> a = -2/2

=> a = -1

Hope it helps u !!!!!!!

Answer 2

Answer:

x=a

Explanation:

x8-ax7+x6-ax5+x4-ax3+3x-a+2=0

a8-a(a7)+a6-a(a5)+a4-a(a3)+3(a)-a+2=0
