Question

( x ^2 - 4 )/ x = 3

how did this part happened? ( from step no.2)

Answer 1

ii think this question is wrong

Answer 2

Answer:

x = -1 or x = 4

Step-by-step explanation:

( x^2 - 4 )/ x = 3

x^2 - 4  = 3 x

x^2 - 4 - 3 x = 0

x^2 - 3 x - 4 = 0

Solve this equation by splitting middle term

x^2 -4 x + x - 4 = 0

Take common

x (x - 4) +1 (x - 4) = 0

(x + 1) (x - 4) = 0

(x + 1) = 0 or (x - 4) = 0

x = -1 or x = 4

Hence the value of x = -1 or x = 4
