[tex](x - 6) \times {x}^{ \frac{1}{2} } (x + 3) \\ (x - 6) \times ({x}^{ \frac{3}{2} } + 3{x}^{ \frac{1}{2} } )\\ {x}^{ \frac{5}{2} } + 3 {x}^{ \frac{3}{2} } - 6 {x}^{ \frac{3}{2} } - 18 {x}^{ \frac{1}{2} } \\ {x}^{ \frac{5}{2} } - 3 {x}^{ \frac{3}{2} } - 18 {x}^{ \frac{1}{2} } \\ \sqrt{ {x}^{5} } - 3 \sqrt{ {x}^{3} } - 18 \sqrt{x} [/tex]
looks like you have the. correct answer selected?
the key here is to remember that
[tex] {x}^{a} \times {x}^{b} = {x}^{a + b} [/tex]
