Answer:4708
Step-by-step explanation:
If consider the expression as
a + b = c
Then it is as follows
{(a*(b+1))*(a+b)}+[b*(b-a)] = c
Step 1. {(2*4)*(2+3)}+[3*(3-2)] = 43
Step 2.{(3*5)*(3+4)}+[4*(4-3)] = 109
Step 3.{(7*10)*(7+9)}+[9*(9-7)] = 1138
Step 4.{(12*15)*(12+14)}+[14*(14-12)] = 4708

12 + 14 = 4708
Step-by-step explanation:
2 + 3 = 43
⇒ {(2 × 4) × (2 + 3)} + [3 × (3 - 2)]
⇒ {(8) × (5)} + [3 × (1)]
⇒ {40} + [3]
∴ 43
3 + 4 = 109
⇒ {(3 × 5) × (3 + 4)} + [4 × (4 - 3)]
⇒ {(15) × (7)} + [4 × (1)]
⇒ {105} + [4]
∴ 109
7 + 9 = 1138
⇒ {(7 × 10) × (7 + 9)} + [9 × (9 - 7)]
⇒ {(70) × (16)} + [9 × (2)]
⇒ {1120} + [18]
∴ 1138
12 + 14 = ?
⇒ {(12 × 15) × (12 + 14)} + [14 × (14 - 12)]
⇒ {(180) × (26)} + [14 × (2)]
⇒ {4680} + [28]
∴ 4708
