If one of root of equation `x^2-ax+1=0` is `infty`, n or root is
Solution:
Let, `alpha`, `beta ` be the two roots such that `beta=infty`
Now,
`alpha* beta=c/a`
or, `alpha=1/beta`
or, `alpha=1/infty`
If A is a square matrix, which of the following is true ?
The area of triangle formed by the lines `x=0`, `y+x=0`, and `x-c=0` is
