Пожалуйста помогите побыстрее!

Answer 1

5.36

$1) {m}^{2} - 9 \ 2) {c}^{2} - 49 \ 3) {25a}^{2} - 16 \ 4) {49x}^{2} - 4$

$5) {25a}^{2} - {64b}^{2} \ 6) {100p}^{2} - 36 {q}^{2}$

5.37

$1) - {c}^{2} + {d}^{2} = {d}^{2} - {c}^{2} \ 2) - {a}^{2} - {b}^{2}$

Answer 2

m^2-9

c^2-49

25a^2-16

49x^2-4

25a^2-64b^2

100p^2-36q^2
