Question

Can anyone solve this problem​

Answer 1

`10(x - a) \\`

Explanation:

`\sqrt{ {x}^(2) - {a}^(2) } \sqrt{ (10)/(a + x) } \\ = {( \sqrt{ {x}^(2) - {a}^(2) } \sqrt{ (10)/(a + x) })}^(2) \\ = ({x }^(2) - {a}^(2) ) * ( (10)/(a + x) ) \\ = (x - a)(x + a) * (10)/(a + x) \\ = (x - a) * 10 \\ = 10(x - a) \\`
