(4b + 8)²
(3 + x)²
(8 + 12k)²
(10k + 12p)²
(1 + s)²
??? ayuda

Answer 1

Solución

$(1 + 5x)² = 25 {x}^{2} + 10x + 1$

$(7x + 2y)² = 49 {x}^{2} + 28xy + 4 {y}^{2}$

$(9m + n)² = 81 {m}^{2} + 18mn + {n}^{2}$

$(5t + 4s)² = 25 {t}^{2} + 40st + 16 {s}^{2}$

$(4b + 8)² = 16 {b}^{2} + 64b + 64$

$(3 + x)² = {x}^{2} + 6x + 9$

$(8 + 12k)² = 144 {k}^{2} + 192k + 64$

$(10k + 12p)² = 100 {k}^{2} + 240kp + 144 {p}^{2}$

$(1 + s)² = {s}^{2} + 2s + 1$
