Answer:

2x\sqrt{40x}-2x\sqrt{5}

Step-by-step explanation:

2x\sqrt{40x}-2x\sqrt{5} is found by first, siplifying the radicals in the parenthesis. \sqrt{8x^{2} } can be simplified as 2x\sqrt{2} and -2\sqrt{x} stays the same. Now we have to multiply these two by \sqrt{5x} which then results in 2x\sqrt{40x}-2x\sqrt{5}
