Answer 1

Step-by-step explanation:

(x²-5) (x+5) +25

\begin{gathered} = > x {}^{3} + 5x {}^{2} - 5x - 25 + 25 \\ \\ = > x {}^{3} + 5x { }^{2} - 5x.\end{gathered}

=>x

−5x.

Answer 2

Answer:

x^3 + 5x^2 - 5x

Step-by-step explanation:

= x^2(x+5) - 5(x+5) + 25

= (x^2 X x) + (x^2 X 5) - (5 X x) - (5 X 5) + 25

= x^3 + 5x^2 - 5x - 25 + 25

= x^3 + 5x^2 - 5x
