Show that the statement p: “If x is a real number such that x^3 + 4x = 0, then x is 0” is true by method of contrapositive

Let

   

‘In case

   

is a genuine number to such an extent that

   

then, at that point,

   

   

is a genuine number to such an extent that

   

   

By contrapositive strategy, to show proclamation

   

to be valid, we expect that

   

is bogus and prove that

   

should be bougus

   

Unmistakably, it tends to be seen that

   

will consistently be positive

   

infers that the result of any sure genuine number with

   

isn’t zero.

Presently, consider the result of

   

with

   

   

This shows that assertion

   

isn’t correct.

Thus, demonstrated that

   

Thus, the given assertion

   

is valid.
