Answer:
x= -1 or x= -1/2
Explanation:
x = -1, x = -1/2, Solve for x:
2 x^2 + 3 x + 1 = 0
The left hand side factors into a product with two terms:
(x + 1) (2 x + 1) = 0
Split into two equations:
x + 1 = 0 or 2 x + 1 = 0
Subtract 1 from both sides:
x = -1 or 2 x + 1 = 0
Subtract 1 from both sides:
x = -1 or 2 x = -1
Divide both sides by 2:
x = -1 or x = -1/2
