Explanation Given information: Given expression is 4 + h − 2 h Calculation: To rationalize the numerator the expression is multiplied by the conjugate of the denominator in the numerator and denominator. The expressions a + b and a − b are said to be the conjugates of each other. Here, the conjugate of 4 + h − 2 is 4 + h + 2 Hence, the expression is written as, 4 + h − 2 h = ( 4 + h − 2 ) ( 4 + h + 2 ) ( h ) ( 4 + h + 2 ) 4 + h − 2 h = ( 4 +
