Question

Solve the following expression -: Subtract the sum of (4+u) (u²+7) from the sum of (6+u+u²) (8u+3)​

Answer 1

Answer:

$(6 + u + {u}^{2} ) \times (8u + 3) - (4 + u) \times ( {u}^{2} + 7) \\ \\ = (51u + 11 {u}^{2} + 8 {u}^3 + 18) - (4 {u}^{2} + 28 + {u} ^{3} + 7u) \\ = 44u +7 {u}^{2} + 7 {u}^{3} - 10 \\ \\ hope \: it \: helps \: you \\ thanks \: you$
