Question

multiply (root 3 - 7 root 3) x (2 root 5 + root 2)

Answer 1

Step-by-step explanation:

$( \sqrt{3} - 7 \sqrt{3} )(2 \sqrt{5} + \sqrt{2} )$

$2 \sqrt{15} - \sqrt{6} - 14 \sqrt{15} - 7 \sqrt{6}$

$- 12 \sqrt{15} - 8 \sqrt{16}$

Answer 2

$\huge {\mathcal{\purple{A}\green{N}\pink{S}\blue{W}\purple{E}\green{R}\pink{!}}}$

$( \sqrt{3} - 7 \sqrt{3} ) \times (2 \sqrt{5} + \sqrt{2} ) \\ \\ = \sqrt{3} \times (2 \sqrt{5} + \sqrt{2} ) - 7 \sqrt{3} \times (2 \sqrt{5} + \sqrt{2} ) \\ \\ = 2 \sqrt{15} + \sqrt{6} - (14 \sqrt{15} + 7 \sqrt{6} ) \\ \\ = 2 \sqrt{15} + \sqrt{6} - 14 \sqrt{15} - 7 \sqrt{6} \\ \\ = 2 \sqrt{15} - 14 \sqrt{15} + \sqrt{6} - 7 \sqrt{6} \\ \\ = - 12 \sqrt{15} - 6 \sqrt{6}$
