step-by-step explanation:

answer:

see explanation

step-by-step explanation:

this is a quadratic equation

rearrange into standard form : ax² + bx + c = 0 : a ≠ 0

subtract 20e from both sides

25e² - 20e + 4 = 0 ← in standard form

this is a perfect square of the form

(a - b)² = a² - 2ab + b²

25e² = (5e)² ⇒ a = 5e and 4 = 2² ⇒ b = 2, and

- 2ab = - 2 × 5e × 2 = - 20e, hence

25e² - 20e + 4 = (5e - 2)²

⇒ (5e - 2)² = 0 ⇒ e = with multiplicity 2
