Question

a) $(x+3)(x+10)$

d) $(y+5)^{2}$

g)$(x+3)(x-3)$

Answer 1

$\bf \textcolor{cyan}{(x + 3)(x + 10) = } \\ \\ \bf \textcolor{cyan}{ {x}^{2} + 10x + 3x + 30 = } \\ \\ \boxed {{x}^{2} + 13x + 30}$

$\bf \textcolor{green}{(y + 5)^{2} = } \\ \\ \bf \textcolor{green}{ {y}^{2} + 5y + 5y + 25 = } \\ \\ \boxed { {y}^{2} + 10y + 25}$

$\bf \textcolor{orange}{(x + 3)(x - 3) = } \\ \\ \bf \textcolor{orange}{ {x}^{2} - 3x + 3x - 9 = } \\ \\ \boxed { {x}^{2} - 9}$
