Answer:
A
Step-by-step explanation:
Given
- 1 ← a difference of squares which factors in general as
a² - b² = (a - b)(a + b)
here = (x²)² ⇒ a = x² and b = 1
- 1 = (x² - 1)(x² + 1)
x² - 1 ← is a difference of squares and factors as
x² - 1 = (x - 1)(x + 1), so
(x² - 1)(x² + 1) = (x - 1)(x + 1)(x² + 1), hence
- 1 = (x - 1)(x + 1)(x² + 1) → A
Answer:
BC = =12
Step-by-step explanation:
if the triangle is ABC and have part 12
and right angle from B and have an angle 45 then the third angle is 45 too
then we have another part is 12
and the BC = =12
