Question

determine by substitution if -5 is the root of x-5=0

Answer 1

Step-by-step explanation:

Let, -5 is the root of the given equation.

So, therefore, x = -5

Now put the value of x in equation,

Therefore, x-5=0

LHS= x-5

= -5-5

= -10

Thus, -10 is not equal to 0

So, -5 is not the root of given equation.
