Question

(4+√2)[3-√2)


help me out​

Answer 1

Answer:

10-root 2 is the right answer

Answer 2

$(4 + \sqrt{2} )(3 - \sqrt{2} )$

$4(3 - \sqrt{2} ) + \sqrt{2} (3 - \sqrt{2})$

$12 - 4 \sqrt{2} + 3 \sqrt{2} - \sqrt{4}$

$12 - 4 \sqrt{2} + 3 \sqrt{2} - 2$

$10 - 4 \sqrt{2} + 3 \sqrt{2}$

$10 - \sqrt{2}$
