Part 1) Problem Statement
You are a civil engineer and want to find the natural frequency of a structure you are designing. In order to determine this frequency it is necessary to use the quadratic equation to solve for the roots of: Ax^2+Bx+C=0

where: A= 100 B=-1.15x10^4 C=2.7x10^5, ?(subscript n)=?x

Hint: Use the quadratic formula. The MATLAB command sqrt() can be used to take the square root of a value. The two solutions, x, to the quadratic equation are real and positive. To determine the two natural frequencies, ?(subscript n) , take the square root of the x values.

Here are the steps:
1. Assign values to variables A, B, and C for Part #1. (I know to assign these I have to put A = 100; B =-1.15

Explanation / Answer

A = 100; B =-1.15*(10^4); C = 2.7((10^5); X1 = ((-B)+sqrt((B^2)-(4*A*C)))/(2*A) X2 = ((-B)-sqrt((B^2)-(4*A*C)))/(2*A)
