Answer:

x = -1 ± √6 / 5

Step-by-step explanation:

Solve [tex]5x^{2}[/tex] + 2x = 1

move 1 to the left side of the equation by subtracting it from both sides.

[tex]5x^{2}[/tex] + 2x - 1 = 0

Use the quadratic formula to find the solutions.

-b± [tex]\sqrt{b^2 - 4 (ac)}[/tex]/ 2a

Substitute the values a = 5 , b = 2, and c = -1 into the quadratic formula and solve for x

-2±[tex]\sqrt{2^2 - 4(5 - 1)}[/tex]/ 2 ⋅ 5

Simplify.

x = -2 ± 2 [tex]\sqrt{6}[/tex]/ 10

x = -1 ± [tex]\sqrt{6}[/tex]/ 5

Exact Form:

x = -1 ± [tex]\sqrt{6}[/tex]/ 5
