Question

find the value of a for which the polynomial 2 X square + a x + root 2 has 1 as its 0

Answer 1

substitute x=1 put the values and then solve the equation...

Answer 2

Answer:

a = - ( 2 + √2 )

Step-by-step explanation:

Given that;

For x = 1, the polynomial 2x² + ax + √2 = 0.

p(x) = 2x² + ax + √2 = 0

⇒ 2 (1)² + a * 1 + √2 = 0

⇒ 2 + a + √2 = 0

⇒ a = - ( 2 + √2 )

Hence, the value of of a is - ( 2 + √2 ).
