a) 2x²- 4x-6 = 0
2(x²-2x-3) = 0
x → -3
x → 1
(x-3) (x+1) = 0
x-3 x+1 = 0
Respuesta → (x = 3) (x = -1)
b) x²-3/4x = 9/8
8x²-6x = 9
8x²-6x-9 = 0
2x → 3
4x → -3
(2x-3) = 0 (4x+3) = 0
2x-3 = 0 4x+3 = 0
Respuesta → (x = 3/2) (x = -3/4)
c) 4x²-6x+2 = 0
2(x²-3x+1) = 0
2x²-3x+1 = 0
2x → -1
x → -1
(2x-1) = 0 (x-1) = 0
2x-1 = 0 x-1 = 0
Respuesta → (x = 1/2) (x = 1)
d) x²-3x-4 = 0
x → -4
(x-4) (x+1) = 0
Respuesta → (x = 4) (x = -1)
Espero haberte ayudado, Salu2!!!
