If one zero of the polynomia 2x square+px+4 is 2 . Find the value of p

1.	If one zero of the polynomia 2x square+px+4 is 2 . Find the value of p.
Answer» ANSWER: - 6 Step-by-step explanation: If 2 is a ZERO of this POLYNOMIAL, NUMERIC value of this polynomial should be 0 for x = 2. Therefore, ⇒ 2( 2 )^2 + p( 2 ) + 4 = 0 ⇒ 2( 4 ) + 2p + 4 = 0 ⇒ 8 + 2p + 4 = 0 ⇒ 12 + 2p = 0 ⇒ 2p = - 12 ⇒ p = - 12 / 2 ⇒ p = - 6

If one zero of the polynomia 2x square+px+4 is 2 . Find the value of p.

Answer»

ANSWER:

- 6

Step-by-step explanation:

If 2 is a ZERO of this POLYNOMIAL, NUMERIC value of this polynomial should be 0 for x = 2.

Therefore,

⇒ 2( 2 )^2 + p( 2 ) + 4 = 0

⇒ 2( 4 ) + 2p + 4 = 0

⇒ 8 + 2p + 4 = 0

⇒ 12 + 2p = 0

⇒ 2p = - 12

⇒ p = - 12 / 2

⇒ p = - 6
