Question

find the value of a , if x-1 is a factor of 2xsquare+ax+root 2

Answer 1

Answer:

-(2+√2)

Step-by-step explanation:

we have, 2x²+ax+√2 = 0 ..... (1)

so, it is given that this eq. is a factor of x-1

so, x-1 = 0

x = 1

by putting it in eq. 1

2(1)²+a(1)+√2 = 0

a+2+√2 = 0

so, a = -(2+√2) ....ans.
