Answer: x = ±
(1)/(2)

Explanation:

Equation:

4x² + 10 = 11 > bring everything over to other side

> first subtract 10 from both sides

4x² = 1 > Divide by 4 on both sides

x² =
(1)/(4) >Take square root of both sides

> When you take square root there is a ±

x = ±
\sqrt{((1)/(4) )} > take the square root of both top and bottom

x = ±
(1)/(2)
