Question

(3-√2) (3+√3)equals​

Answer 1

Answer:

(3-√2) (3+√3)equals =7.5040219928

Answer 2

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

We know an algebraic identity,

$(x + a)(x + b) = {x}^{2} + (a + b)x + ab$

Here

$x = 3 \\ a = - \sqrt{2} \\ b = \sqrt{3}$

Now substitute the values

${(3)}^{2} + ( - \sqrt{2} + \sqrt{3} )x + ( - \sqrt{2} )( \sqrt{3}) \\ 9 + ( \sqrt{3 } - \sqrt{2} )x + ( - \sqrt{6} ) \\ 9 + \sqrt{3} x - \sqrt{2} x - \sqrt{6}$
