Which are the solutions of x2 = –5x + 8?

x=1.53

x=6.53

Step-by-step explanation:

The first thing to do is to leave the equation equal to zero expressed.

Next, being a second degree equation, we can use the general formula to find the solutions. This equation is as follows:

Where a is the coefficient of the quadratic term, b the coefficient of the linear term and c the coefficient of the value without variable.

In this case:  a=1, b=5, c=-8

Replacing in the ecuation

Now

So, both solution:

x=1.53

x=6.53

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
