A quadratic equation which goes through the origin has the form y

A quadratic equation which goes through the origin has the form y = cx + dx and it goes through the points (1, 143), (2, 143),(-1,143) First setup the system such that it takes the form Ax=b; convince yourself that this system is inconsistent. Then use the method of least squares to find the following. Find the value of c. Find the value of d. What is magnitude of the orthogonal projection of the error on the column space of A ?
