Б. Найдите значение выражения при данных значениях переменных а и в:

a = 1, b = 1a = 2, b = -1a = -1, b = -3
1) 2a + b\( 2(1) + 1 = 2 + 1 = 3 \)\( 2(2) + (-1) = 4 - 1 = 3 \)\( 2(-1) + (-3) = -2 - 3 = -5 \)
2) 2(a + b)\( 2(1 + 1) = 2(2) = 4 \)\( 2(2 + (-1)) = 2(1) = 2 \)\( 2(-1 + (-3)) = 2(-4) = -8 \)
3) 2a + b2\( 2(1) + 1^2 = 2 + 1 = 3 \)\( 2(2) + (-1)^2 = 4 + 1 = 5 \)\( 2(-1) + (-3)^2 = -2 + 9 = 7 \)
4) 2(a + b2)\( 2(1 + 1^2) = 2(1 + 1) = 2(2) = 4 \)\( 2(2 + (-1)^2) = 2(2 + 1) = 2(3) = 6 \)\( 2(-1 + (-3)^2) = 2(-1 + 9) = 2(8) = 16 \)
5) 2(a + b)2\( 2(1 + 1)^2 = 2(2)^2 = 2(4) = 8 \)\( 2(2 + (-1))^2 = 2(1)^2 = 2(1) = 2 \)\( 2(-1 + (-3))^2 = 2(-4)^2 = 2(16) = 32 \)
6) 2a2 + b\( 2(1)^2 + 1 = 2(1) + 1 = 2 + 1 = 3 \)\( 2(2)^2 + (-1) = 2(4) - 1 = 8 - 1 = 7 \)\( 2(-1)^2 + (-3) = 2(1) - 3 = 2 - 3 = -1 \)
7) 2(a2 + b)\( 2(1^2 + 1) = 2(1 + 1) = 2(2) = 4 \)\( 2(2^2 + (-1)) = 2(4 - 1) = 2(3) = 6 \)\( 2((-1)^2 + (-3)) = 2(1 - 3) = 2(-2) = -4 \)
8) 2a2 + b2\( 2(1)^2 + 1^2 = 2(1) + 1 = 2 + 1 = 3 \)\( 2(2)^2 + (-1)^2 = 2(4) + 1 = 8 + 1 = 9 \)\( 2(-1)^2 + (-3)^2 = 2(1) + 9 = 2 + 9 = 11 \)
