Question

(X ² - 5 ) (X+5 ) +. 25​

Answer 1

Step-by-step explanation:

(x2 - 5) |( x - 5) + 25

= x2 (x + 5) -5 ( x 5) + 25

=(x2 X x ) + (x2 x 5) -( 5 X x) - (5 x 5) + 25

= x3 + 5x2 - 5x -25 + 25

= x3 + 5x2 - 5x.

Answer 2

Answer=$x^{3\\}$+5x²-5x +25

Step-by-step explanation =(x² - 5) ( x - 5) + 25

                                            = x² (x + 5) -5 ( x-5) + 25

                                            = $x^{3\\}$ +5x²-5x +25 +25

                                            =$x^{3\\}$ +5x²-5x +50
