Question

if 2x + 5 is a factor of 2x^2 - K find the value of K​

Answer 1

Answer:

Step-by-step explanation:

Given:

2x + 5 is the Factor.

= 2x + 5 = 0

= x = -5/2

P(x) = 2x² - k

= P(-5/2) = 2(-5/2)² - k

= 0 = 2( 25/4) - k

= K = 25/2

Hence,

K = 25/2.

Answer 2

Answer:

${\huge\boxed{\bf{\blue{\mathbb{YOUR\:ANSWER}}}}}$

2x + 5 is the factor.

2x + 5 = 0

x = - 5/2

P(x) = 2x² - K

P (-5/2) = 2 (-5/2)² - K

0 = 2 (25/4) - K

K = 25/4
