Answer 1

Answer:

1. 59$ab^{2}$

2. 12a + 6b - 13c

Answer 2

Answer 1 -

• 4 + 3a²b + 12ab².

To find -

• The value of 7 + 5a²b - 6ab² + 9 + 3ab² - 2a²b - 12 + 15ab².

Step-by-step explanation -

$\longmapsto$ 7 + 5a²b - 6ab² + 9 + 3ab² - 2a²b - 12 + 15ab²

$\longmapsto$ 7 + 9 - 12 + 5a²b - 2a²b - 6ab² + 3ab² + 15ab²

$\longmapsto$ 4 + 3a²b + 12ab²

Answer 2 -

• 12a + 4b - c.

To find -

• The value of 8a + 3b - 7c - 7a + 2b - 3c + 9c + 11a - b.

Step-by-step explanation -

$\longmapsto$ 8a + 3b - 7c - 7a + 2b - 3c + 9c + 11a - b

$\longmapsto$ 8a - 7a + 11a + 3b + 2b - b - 7c - 3c + 9c

$\longmapsto$ 12a + 4b - c
