Question

X^4-8x^2+5=5 PORFAVOR RESUELVENLA PORFAVOR

Answer 1

X⁴ - 8x² +5 = 5

X⁴ - 8x² + 5 - 5 = 0

X⁴ - 8x²  = 0

X²(X² - 8) = 0

X² = 0               X² - 8 = 0

√X²  = 0          √X² = √ 8

X = 0                  X = ± 2√2

CS = ( -2√2; 0; 2√2)

Answer 2

${x}^{4} - 8 {x}^{2} + 5 = 5 \\ {x}^{4} - 8 {x}^{2} = 0 \\ {x}^{2} \times ( {x}^{2} - 8) = 0 \\ {x}^{2} = 0 \\ {x}^{2} - 8 = 0 \\ x = 0 \\ x = - 2 \sqrt{2} \\ x = 2 \sqrt{2}$

Solucion: x={0; -2√2;2√2;}
