Question

if (x-2) is a factor of x square -ax+4, the value of a is​

Answer 1

Answer:

4

Step-by-step explanation:

x-2=0

x=2

x²-ax+4=0

2²-2a+4=0

4-2a+4=0

8-2a=0

8=2a

a=8/2

a=4

Hope u got ur answer =)

pls mark me as brainliest

Answer 2

Step-by-step explanation:

since x-2 is factor of x^2-ax+4

therefore, put x= 2

x^2-ax+4 = 0

(2)^2-a2 + 4 = 0

8 = 2a

a = 4

It is your answer
