Solve the equation. Enter the answer in radical form, and then use a calculator to approximate the solution to two decimal places, if necessary.

(x + 5.6) 2 = 1.75

x = - 5.6 ±sqrt (1.75)

x≈-4.28 x≈-6.92

Step-by-step explanation:

(x + 5.6) ^2 = 1.75

Take the square root of each side

sqrt ((x + 5.6) ^2) = ±sqrt (1.75)

x+5.6 = ±sqrt (1.75)

Subtract 5.6 from each side

x+5.6 - 5.6 = - 5.6 ±sqrt (1.75)

x = - 5.6 ±sqrt (1.75)

x = - 5.6 + sqrt (1.75) x = - 5.6 - sqrt (1.75)

x≈-4.27712 x≈-6.92288

x≈-4.28 x≈-6.92

x = sqrt (1.75) - 5.6, - sqrt (1.75) - 5.6,

x ≈ - 4.28, - 6.92

Step-by-step explanation:

(x + 5.6) ² = 1.75

(x + 5.6) = + / - sqrt (1.75)

x = + / - sqrt (1.75) - 5.6

x ≈ - 4.28, - 6.92
