see explanation

Step-by-step explanation:

Given

5x³ + 40 ← factor out 5 from each term

= 5(x³ + 8)

x³ + 8 ← is a sum of cubes and factors in general as

a³ + b³ = (a + b)(a² - ab + b²)

x³ + 8

= x³ + (2y²)³ → a = x and b = 2y²

= (x + 2y²)(x² - 2xy² + 4)

Hence

5x³ + 40

= 5(x + 2y²)(x² - 2xy² + 4) ← in factored form
