Explanation

Given:

(x + 5) : (x + 7) = 5 : 7

We can write it as:

(x + 5) / (x + 7) = 5/7

Cross-multiplying:

7(x + 5) = 5(x + 7)

7x + 35 = 5x + 35

7x - 5x = 35 - 35

2x = 0

x = 0

Explanation

a² - b² = (a - b)(a + b)

a⁴ - b⁴ = (a² - b²)(a² + b²)

= (a - b)(a + b)(a² + b²)

The LCM is (a - b)(a + b)(a² + b²) = (a² - b²)(a² + b²)

= a⁴ - b⁴
