Question

simplify (2x + 5 )² - (2x - 5 )²​

Answer 1

Answer:

(2x +5)² - (2x - 5)²

=> (2x)² + 2(2x)(5) + (5)² - [(2x)² - 2(2x)(5) + (5)²]

=> 4x² + 20x + 25 - [4x² - 20x + 25]

=> 4x² + 20x + 25 - 4x² + 20x - 25

=> 40x

Answer 2

Step-by-step explanation:

˙❥˙= [2x² + 2(2x)(5) + (5)²] - [(2x)²- 2(2x)(5)+(5)²]

= [4x²+20x+25] - [4x²-20x+25]

= [4x²+20x+25] - [4x²-20x+25]= 4x²+20x+25-4x²+20x-25

= [4x²+20x+25] - [4x²-20x+25]= 4x²+20x+25-4x²+20x-25= (4x²-4x²)+(20x+20x)+(25-25)

= [4x²+20x+25] - [4x²-20x+25]= 4x²+20x+25-4x²+20x-25= (4x²-4x²)+(20x+20x)+(25-25)= 0+40x+0

= 40x✧*。
