Answer:
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
