Question

complete o quadro . Me ajudeeeeem .. Me expliquem

Answer 1

$a)(a + b) ^{2} = (5 + 3)^{2} = {8}^{2} = 64 \\ {a}^{2} + {b} +^{2} = {5}^{2} + {3}^{2} = 25 + 9 = 34 \\ \\ b)(a + b)^{2} = (0 + 6)^{2} = {6}^{2} = 36 \\ a^{2} + b^{2} = {0}^{2} + {6}^{2} = 0 + 36 = 36$
$c)(a + b)^{2} = ( {3}+ ( - 1))^{2} =( 3 - 1)^{2} = 2 ^{2} = 4 \\ {a}^{2} + b^{2} = {3}^{2} + ( { - 1})^{2} = 9 + 1 = 10$
$d)(a + b)^{2} = ( - 1 + 4)^{2} = 3^{2} = 9 \\ {a}^{2} + {b}^{2} = { - 1}^{2} + {4}^{2} = 1 + 16 = 17$
