Answer:
(x - 2)(x + 2)
Step-by-step explanation:
x² - 4 ← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b), that is a product of two binomials
Given
x² - 4
= x² - 2²
= (x - 2)(x + 2)
Answer:
how do I not know it not a vires?
Step-by-step explanation:
sin(α) = ⁻⁵/₁₃
sin⁻¹[sin(α)] = sin⁻¹(⁻⁵/₁₃)
α ≈ 1.1256π
cos(β) = ²/₅
cos⁻¹[cos(β)] = cos⁻¹(²/₅)
β ≈ 1.6311π
sin(α - β) = sin(1.1256π - 1.6311π)
sin(α - β) = sin(-0.5055π)
sin(α - β) = -sin(0.5055π)
sin(α - β) = -sin(90.99)
sin(α - β) ≈ -0.116
