The difference of two surds example

1.	The difference of two surds example
Answer» The sum and difference of two simple quadratic surds are SAID to be conjugate surds to each other. ... For EXAMPLE √x = a and √y = B, a and b are two quadratic surds, if (a + b) or (√x+√y) is multiplied with (a - b) or (√x−√y), the result will (√x)2 - (√y)2 or (x - y) which is RATIONAL number.
