Answer:
x = -1 ± √6 / 5
Step-by-step explanation:
Solve
+ 2x = 1
move 1 to the left side of the equation by subtracting it from both sides.
+ 2x - 1 = 0
Use the quadratic formula to find the solutions.
-b±
/ 2a
Substitute the values a = 5 , b = 2, and c = -1 into the quadratic formula and solve for x
-2±
/ 2 ⋅ 5
Simplify.
x = -2 ± 2
/ 10
x = -1 ±
/ 5
Exact Form:
x = -1 ±
/ 5
