Question

If (x-2) is a factor of x²-ax +4 ,then the value of 'a' is. ​

Answer 1

Answer:

Given

f(x)=x^2-ax+4

x-2 is factor oi this,

so x=2

put in f(x)

thus

x^2-ax+4=0

2²-2a+4=0

4-2a+4=0

8-2a=0

-2a=-8

a=-8/-2

a=4 answer

Answer 2

Answer:

If (x-2) is a factor of x²-ax +4 ,then the value of 'a' is.
