Question

rationalize and explain in the form of a and b​

Answer 1

Answer:

a is 3 and b is -√2

Step-by-step explanation:

$\frac{4 + \sqrt{2} }{2 + \sqrt{2} } \: \\ \: \: \: \: \: \: \: \: \: \: \: \: multiply \: both \: the \: numerator \: and \: the \:  denominator \:  by \: the \: conjugate(opposite \: sign) \: of \: the \:  denominator. \\ \frac{4 + \sqrt{2} }{2 + \sqrt{2} } \times \frac{2 - \sqrt{2} }{2 - \sqrt{2} } \\ \frac{(4 + \sqrt{2})(2 - \sqrt{2}) }{ {2}^{2} - { (\sqrt{2} })^{2} } \: \: \: \: \: \: \: \: \: \: \: \: (a + b)(a - b) = {a}^{2} - {b}^{2} \\ \frac{8 - 4 \sqrt{2} + 2 \sqrt{2} - 2}{4 - 2} \\ \frac{6 - 2 \sqrt{2} }{2} \\ \frac{2(3 - \sqrt{2}) }{2} \\ 3 - \sqrt{2}$

we got the answer as a - √b
