Answer 1

Step-by-step explanation:

x-4=0

=. x=4

Now:-

px^3+3x^2-3=0

we substitute value of x :-

p(4)^3+3×(4)^2-3=0

=. 64p+48-3=0

=. 64p+45=0

=. 64p= -45

=. p=. -45/64. Ans.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Again

We substitute value of x:-

2x^3-5x+p=0

=. 2×(4)^3-5×4+p=0

=. 2×64-20+p=0

=. 128-20+p=0

=. 108+p=0

=. p=-108. Ans.
