Students get self-study resources targeted to the needs of individual courses and teachers gain generic mathematics support and study materials for use with students. I dont think its possible finding the matrix representing the transformation. Then I set the original expression equal to the last line from the multiplication above and complete the calculations by simplifying each term.
Find out the conjugate of the number which is to be rationalized.
It will be impossible before you pick a basis. For instance the conjugate of x y is x y. We can also say that x y is a conjugate of x y. Now multiply the conjugate ie 52 5 2 to both numerator and denominator.
