Answer 1

Answer:

$(2a + 3b) {}^{2} \\ \\ 4a {}^{2} + 9b {}^{2} + 12ab$

I hope it helps you

Answer 2

Answer:

${(2a + 3b)}^{2}$

Since

${(x + y)}^{2} = {x}^{2} + 2xy + {y}^{2}$

$x = 2a \\ y = 3b$

$= {x}^{2} + 2xy + {y}^{2}$

${(2a)}^{2} + 2 \times 2a \times 3b + {(3b)}^{2}$

$4 {a}^{2} + 12ab + 9 {b}^{2}$
