Question

2.(a)Check whether x.=-5 is the solution of x²+6x+5. ​

Answer 1

Answer:

Yes

Step-by-step explanation:

Let p(x) = x²+6x+5

If p(-5)=0 then x=-5 is a solution of given polynomial

p(-5) = (-5)²+6(-5)+5

         = 25-30+5

           = 30-30

p(-5) = 0

So x=-5 is the solution of x²+6x+5

Answer 2

Answer:

yes

Step-by-step explanation:

x^2+6x+5

= -5^2+6×(-5)+5

= -5×-5+(-30) +5

= 25-30+5

= -5+5

= 0

So x= - 5 is the solution of the x^2+6x+5
