Question

Determine el cuadrado de suma de dos cantidades
(3+4) ²=
(2a+3b) ²=
(2+5) ² =
(4+6) ² =

Answer 1

${(3 + 4)}^{2} = {3}^{2} + {4}^{2} + 2 \times 3 \times 4 = 9 + 16 + 24 = 49$

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

$(2+5) ² = {2}^{2} + {5}^{2} + 2 \times 2 \times 5 = 4 + 25 + 20 = 49$

${(4 + 6)}^{2} = {4}^{2} + {6}^{2} + 2 \times 4 \times 6 = 16 + 36 + 48 = 100$
