Question

a) 3(2 \sqrt{2} - 5x)-2(x-3 \sqrt{2} )=2(3x \sqrt{2} -4) -8x -10
b)$( \sqrt{3} +1) ^{2} x-(3x-1) \sqrt{3} =5x-12+ \sqrt{3} (5x- \sqrt{12} )$
c)$(x+ \sqrt{5})(8-3 \sqrt{5} ) + 3x \sqrt{6+2 \sqrt{5} } -3-5 \sqrt{5}= \sqrt{5} (1+ \sqrt{5} )x$
d)(2x+1)$\sqrt{4-2 \sqrt{3} } +(2x-1) \sqrt{4+2 \sqrt{3} } = 2\sqrt{3} (4-x \sqrt{3}) +10$
