sqrt(4x) / 2x + 1 = 3
Set domain :
2x + 1 cannot equal 3
2x cannot equal 2 | :2
x cannot equal 1
sqrt(4x) = 3(2x + 1)
sqrt(4x) = 6x + 3
4x = 36x^2 + 9
36x^2 - 4x + 9 / f(x) = ax^2 + bx + c
16-4*36*9
16-1296 = - 1280
There's no solutions in Real Number set.
Answer:
n>−12
Step-by-step explanation:
Add 20
to both sides of the inequality.
n>−32+20
Add −32
and 20
.
n>−12
The result can be shown in multiple forms.
Inequality Form:
n>−12
Interval Notation:
(−12,∞)
