Question

If (x - 3) is a factor of x² - px -15, then the value of p is *


​

Answer 1

Answer

P = 12

Step-by-step explanation:

( x² - px -15 ) / ( x - 3 ) => Remainder = 0

Long Division :

⊥ - using it as the sign for division

x-3 ⊥ x² - px -15  Quotient ( x )

       - x²-3x

         0+(3-p)x  -  15 Quotient ( x+(3-p) )

             (3-p)x  - (3-p)

                        3-p-15  

Remainder = -p-12 = 0

=> p= 12
