HELLO DEAR,
(X+2)(X²+25) - 10X² - 20X
=> (X+2)(X²+25) -10X(X+2)
=> (X+2) [ x²+25-10x ]
=> (x+2) [ x²- 5x - 5x +25 ]
=> (x+2) [x(x-5)-5(x-5) ]
=> (x+2) [ (x-5)(x-5 ]
I HOPE ITS HELP YOU DEAR,
THANKS

Answer:
(x+2) [ (x-5)(x-5 ]
Step-by-step explanation:
(X+2)(X²+25) - 10X² - 20X
=> (X+2)(X²+25) -10X(X+2)
=> (X+2) [ x²+25-10x ]
=> (x+2) [ x²- 5x - 5x +25 ]
=> (x+2) [x(x-5)-5(x-5) ]
=> (x+2) [ (x-5)(x-5 ]
hope this helps
