Question

Determina lq solucion de las siguientes ecuaciones. 8x al 4 + 26x al 2 -15= 0 y la otra es 4x al 4 - 37x al 2 + 9=0

Answer 1

4x^4 + 37x^2 + 9

(4x^2 + 1)(x^2 + 9)

4x^2 + 1 = 0 or x^2 + 9 = 0

4x^2 = -1 or x^2 = -9

x^2 = -1/4 or x^2 = -9

x = sqrt(-1/4) or x = sqrt(-9)

x = sqrt(-1* 1/4) or x = sqrt(-1*9)

x = sqrt(-1)sqrt(1/4) or x = sqrt(-1)sqrt(9)

x = i/2 or x = 3i
