Question

Subtract the sum of 3a+ 5ab + 7b2 + 3 and 2a? – 4ab -3b2 + 7 from 9a– Sab + 1162.​

Answer 1

Sum =

$3a + 5ab + 7 {b}^{2} + 3 + 2a - 4ab - 3 {b}^{2} + 7 \\ = 5a + ab + 4 {b}^{2} + 10$

Difference =

$9a - 5ab + 1162 - (5a + ab + 4 {b}^{2} + 10) \\ = 9a - 5ab + 1162 - 5a - ab - 4 {b}^{2} - 10 \\ = 4a - 6ab - 4 {b}^{2} + 1152$
