Question

x^2-7x+12<|x-4| solve the following inequalities​

Answer 1

Answer:

4

Step-by-step explanation:

the equation means that =

[x-4] - [x^2 -7x+12]  = 0

so, [x-4] =  [x^2 -7x+12]

so, x^2 -8x +16 = 0

use the formulae.

if ax^2 - bx+c =0

then , x = (-b) +/- [ (b^2 - 4ac)^0.5 ]   / 2a

so, x = 8 +/- (8^2 -(4*1*16) / (2*1)

so, x= 8/2

so, x = 4
