What are the solutions of the equation x4 – 5x2 – 14 = 0? use factoring to solve.

 The required solutions of the given equation are

Step-by-step explanation:  We are given to find the solutions of the following bi-quadratic equation :

Let us consider that

So, equation (i) becomes

which is a quadratic equation in the variable y. The above equation in variable y can be solved using factorization as follows :

Therefore, we get

and

Thus, the required solutions of the given equation are

2 x t divided by n

step-by-step explanation:

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
