Answer 2

Answer:

Step-by-step explanation:

Given,

Let p ( x ) =x square - 3x - 28

If p ( x )divided by g ( x ) = x - 7 = 0 ⇒ x = 7.

Now substituting " x = 7 " in p ( x ),we get

p ( 7 ) = ( 7 ) square - (3 × 7 ) - 28

= 49 - 21 - 28

= 49 - 49 ( ∵ - 21 - 28 = - 49 addition )

= 0

p ( 7 ) = 0 is the answer.
