Answer 1

Respuesta:

$1) {(3q - 5 {p}^{2} )}^{2} = \\ {(3q)}^{2} + {(5 {p}^{2} )}^{2} - 2 \times 3q \times 5 {p}^{2} = \\ 9{q}^{2} + 25 {p}^{4} - 30 {p}^{2} q$

$2) {(6mn + 4)}^{2} = \\ {(6mn)}^{2} + {4}^{2} + 2 \times 6mn \times 4 = \\ 36 {m}^{2} {n}^{2} + 16 + 48mn$

$3) {(8c + 9d)}^{2} = \\ {(8c)}^{2} + {(9d)}^{2} + 2 \times 8c \times 9d = \\ 64 {c}^{2} + 81 {d}^{2} + 144cd$

Explicación paso a paso:

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

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