tolong jawab beserta jlnnya ya

[tex] \frac{2( {x + 3)}^{2} }{ {x}^{2} + 8x + 15 } \\ = \frac{2( {x }^{2} + 6x + 9)}{ {x}^{2} + 8x + 15 } \\ = \frac{2(x + 3)(x + 3)}{(x + 3)(x + 5)}[/tex]
(x+3) dicoret dg (x+3)

maka sisanya
[tex] \frac{2(x + 3)}{(x + 5)} [/tex]
masukkan nilai x=1
[tex] \frac{2(1 + 3)}{(1 + 5)} = \frac{2.4}{6} = \frac{8}{6} = \frac{4}{3} [/tex]
