Answer :
Step-by-step explanation:
check your question it's f(x) = 12x² - 3
Given :- f(x) = 12x² - 3
- f(x) = 12x² + 3 = 12x² - 3 / 12
- f(x) = 12x²/12 - 3 /12
- f(x) = x² - 1/4
- f(x) = x² + 1/2x - 1/2x -1/4
- f(x) = x( x + 1/2) - 1/2 ( x + 1/2)
- f(x) = (x +1/2) (x -1/2) = 0
- x+ 1/2 = 0 , x - 1/2 = 0
- x = -1/2, x = 1/2 ..
Value of x = 1/2 and x = -1/2 .
Answer:
x = ±1/2
Step-by-step explanation:
To find the zeros of a function f(x), set f(x) = 0 and solve for x.
f(x) = 12x² − 3
Set f(x) = 0.
0 = 12x² − 3
Add 3 to both sides.
3 = 12x²
Divide both sides by 12.
3/12 = x²
1/4 = x²
Take square root of both sides.
x = ±√(1/4)
x = ±1/2
