What are the solutions of the equation x4 + 6x2 + 5 = 0? Use u substitution to solve.
klio [65]

Answer:

x = i and x = i\sqrt{5}

Step-by-step explanation:

Given

x^{4} + 6x² + 5 = 0

Using the substitution u = x², then

u² + 6u + 5 = 0 ← in standard form

(u + 1)(u + 5) = 0 ← in factored form

Equate each factor to zero and solve for u

u + 1 = 0 ⇒ u = - 1

u + 5 = 0 ⇒ u = - 5

Convert solutions back into terms of x

x² = - 1 ⇒ x = \sqrt{-1} = i

x² = - 5 ⇒ x = \sqrt{-5} = i\sqrt{5}

8.) a round patio is 14m in diameter. What is the distance around the patio? A. 153.86m B. 21.98m C. 43.96m D. 615.44m
professor190 [17]
So by having a circle with a diameter of 14 metres it is a sake of calculating the circumference of the patio. This is simply done by (where d = 2r, d is the diameter, and r the radius)

C = 2\pi r = 2\cdot \pi \cdot \left \frac{14}{2} \text{ m} \approx 43.98 \text{ m}
