Question

If p(x) = 2x² -3√2 x -9 then lind p (3√2) =?​

Answer 1

Answer:

p(3√2) = 9

Explanation:

Given:

• p(x) = 2x² -3√2 x -9

To find:

• The value of p(3√2)

Proof:

p(x) = 2x² -3√2 x -9

Putting x= 3√2 in p(x), we get:

= p(3√2) = 2(3√2)² -3√2 ( 3√2 ) -9

⇒ p(3√2) = 2 ( 9 × 2 ) - (3√2)² -9

⇒ p(3√2) = 2 (18) - ( 9 × 2 ) -9

⇒ p(3√2) = 36- 18 -9

⇒ p(3√2) = 36 - 27

⇒ p(3√2) = 9

Hope you got that.

Thank You.
