Find the difference.

(4x3−12x2−5)−(−8x2+4x+3)=

4x³ - 4x² - 4x -8  

Step-by-step explanation:

It is given that,

4x³ - 12x² - 5 -(-8x² + 4x + 3) (1)

This expression shows the subtraction of two algebraic expression.

Let eq(1) 4x³ - 12x² - 5 -(-8x² + 4x + 3)

⇒4x³ - 12x² - 5 +8x² - 4x - 3  (open bracket)

= 4x³ - 12x² + 8x² - 4x -5 -3  (write similar terms together)

= 4x³ - 4x² - 4x -8  

Therefore the difference of 4x³ - 12x² - 5 -(-8x² + 4x + 3) is given by,

4x³ - 4x² - 4x -8
