Question

Plz help mememeemee!!!!

Answer 1

Given that (x + a) is the factor,

So, x = -a 

====================

By Remainder Theorem,


2x^2 + 2ax + 5x + 10 = 0 

2(-a)^2 + 2a(-a) + 5(-a)  + 10 = 0 

2a^2 - 2a^2 - 5a + 10 = 0 

-5a + 10 = 0 

10 = 5a 

10/5 = a 

2 = a 




i hope this will help you

Answer 2

Hey!

[ Refer the attachment ]

a = 2

• It is given that x + a is the factor , so if we divide the polynomial we get zero as resultant.

here , by dividing we get ( 10 - 5a )
So, we equate the remainder by 0.
