3/4s² + 1/2s + 1/12 = 0
12(3/4s²) + 12(1/2s) 12(1/12) = 0
9s² + 6s + 1. . . .The Equation
(3s + 1)(3s + 1). . .The factor
- - - - - - -
Roots
3s = - 1
3s/3 = - 1/3
s = - 1/3
The answer is s = - 1/3
- - - - - - - - - - - - - - - -
Quadratic Formula
x = -b ± √b² - 4ac/2a
The equation
9s² + 6s + 1
A = 9
b = 6
c = 1
X = - 6 ± √(6)² - 4(9)(1)/2(9)
x = - 6 ± √36 - 36/18
x = - 6 ± √0 /18
x = - 6 ± 0 / 18
X = - 6/18
x = - 1/3
The answer is x = - 1/3
