Answer» For polynomial 2x^2 + ax + sqroot(2) has 1 as its zero Then for x = 1 given polynomial should be equal to 0 Thus,211 + a*1 + sqroot(2) = 03 + a + sqroot(2) = 0a = - 3 - sqroot(2)

Answer»

For polynomial 2x^2 + ax + sqroot(2) has 1 as its zero

Then for x = 1 given polynomial should be equal to 0

Thus,2*1*1 + a*1 + sqroot(2) = 03 + a + sqroot(2) = 0a = - 3 - sqroot(2)
