Help me solve this question and thanks !

Answer 1

Answer:

Step-by-step explanation:

x^2+8x+15

=x^2+(5+3)x+15

=x^2+5x+3x+15

=x(x+5)+3(x+5)

=(x+5)(x+3)

Answer 2

$(x + 3)(x + 5)$ ✅

$\large\mathfrak{{\pmb{\underline{\red{Step-by-step\:explanation}}{\orange{:}}}}}$

${x}^{2} + 8x + 15 \\ ={x}^{2} + 5x + 3x + 15$

Taking $x$ as common from first two terms and 3 from last two terms, we have

$=x(x + 5) + 3(x + 5)$

Taking the factor $(x+5)$ as common,

$= (x + 3)(x + 5)$
