Answer 1

Step-by-step explanation:

this is your right answer

Answer 2

here there are 2 expressions:

1 expression = (x²-5)(x+5)

2 expression =25

solving 1 expression:

(x²-5)(x+5)

x²(x+5)-5(x+5)

(x²×x)+(x²×5)-(-5×x)+(-5×5)

x³+5x²+5x-25

Now our expression is:

(x²-5)(x+5)+25

x³+5x²+5x-25+25

x³+5x²+5x
