Answer:
Explanation:
(x - 10)² is not an equation. It is in factorized form. If you do not mention the equals sign, then that is not an equation. But however, this factorized form can be converted to expanded form using Algberaic formulae. The formulae are,
(a - b)² = a² - 2ab + b², (a + b)² = a² + 2ab + b²
According to the question,
a = x and b = 10
(x - 10)² = x² - 2 (x)(10) + 10²
= x² - 20x + 100
x² - 20x + 100 is the expanded form of (x - 10)².
