Answer 2

Answer:

Required addition is $2 \frac{29}{30}$

Step-by-step explanation:

Given,

$\frac{5}{2} + \frac{7}{15}$

It is a problem of Fraction of Algebra.

By Fraction's addition rule,we can solve this problem.

First we are calculating LCM of 2 and 15,

$\frac{5 \times \frac{30}{2} + 7 \times \frac{30}{15} }{30} \\ = \frac{5 \times 15 + 7 \times 2}{30} \\ = \frac{75 + 14}{30} \\ = \frac{89}{30} \\ = 2 \frac{29}{30}$

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)
