0=x^2+4x+10 Rewrite the function by completing the square.

x = -2 ± i√6

Step-by-step explanation:

Simplify the equation into a proper form to complete the square.

-10 = x² + 4x

To create a trinomial square on the left side of the equation, find a value that is equal to the square of half of b

Add the term to each side of the equation.

-10 + 2² = x² + 4x + 2²

Simplify the equation.

-6 = x² + 4x + 4

Factor the perfect trinomial square into (x + 2)²

(x + 2)² = -6

Solve for x.

x = -2 ± i√6

good luck, hope this helps :)
