~Jawab~
x₁² + x₂² = (x₁ + x₂)² - 2x₁x₂
maka,
x₁⁴ + x₂⁴ = (x₁² + x₂²)² - 2x₁²x₂²
Semoga Bermanfaat!
x₁⁴+x₂⁴ = (x₁²)²+(x₂²)²
= (x₁²+x₂²)² - 2.(x₁²).(x₂²)
x₁⁴+x₂⁴ = ((x₁+x₂)²-2.x₁.x₂)² - 2.(x₁.x₂)²

~Jawab~
Persamaan Kuadrat
x₁² + x₂² = (x₁ + x₂)² - 2x₁x₂
maka,
x₁⁴ + x₂⁴ = (x₁² + x₂²)² - 2x₁²x₂²
Semoga Bermanfaat!
x₁⁴+x₂⁴ = (x₁²)²+(x₂²)²
= (x₁²+x₂²)² - 2.(x₁²).(x₂²)
x₁⁴+x₂⁴ = ((x₁+x₂)²-2.x₁.x₂)² - 2.(x₁.x₂)²
