Answer 2

Answer:

Required value of 19/5 + (-7/5) is $2 \frac{2}{5}$

Step-by-step explanation:

Given,

$\frac{19}{5} + ( - \frac{7}{5} )$

This is a problem of fraction of Algebra.

By fraction's rule we can solve this.

$= \frac{19}{5} - \frac{7}{5}$

$= \frac{19 - 7}{5}$

We are Subtracting 7 from 19 and get,

$= \frac{12}{5} \\ = 2 \frac{2}{5}$

Value of 19/5 + (-7/5) is $2 \frac{2}{5}$

This is a problem of Algebra.

Some important Algebra formulas.

(a + b)² = a² + 2ab + b²

(a − b)² = a² − 2ab − b²

(a + b)³ = a³ + 3a²b + 3ab² + b³

(a - b)³ = a³ - 3a²b + 3ab² - b³

a³ + b³ = (a + b)³ − 3ab(a + b)

a³ - b³ = (a -b)³ + 3ab(a - b)

a² − b² = (a + b)(a − b)

a² + b² = (a + b)² − 2ab

a² + b² = (a − b)² + 2ab

a³ − b³ = (a − b)(a² + ab + b²)

a³ + b³ = (a + b)(a² − ab + b²)
