Question

Describe the operations you can use to solve the equation x^2 + 5= 86. Then determine the solution.

Answer 1

To solve the equation x^2 + 5 = 86, we need to isolate the variable x on one side of the equation. We can do this by performing the opposite operations on each side of the equation.

Subtract 5 from both sides of the equation:

x^2 = 81

Take the square root of both sides of the equation:

x = ±9

Therefore, the solutions to the equation x^2 + 5 = 86 are x = 9 and x = -9.

Answer 2

see explanation

Explanation:

One method of solution is given below

x² + 5 = 86 ( subtract 5 from both sides )

x² = 81 ( take the square root of both sides )

x = ±
`√(81)` = ± 9
