simplify-2(3a^2+a-2b)+9(a+4b)+6a^2

simplify

- 2 (3 a^{2} + a - 2 b) + 9 (a + 4 b) + 6 a^{2}

7 a + 40 b

Solution steps

- 2 (3 a^{2} + a - 2 b) + 9 (a + 4 b) + 6 a^{2}

Expand

- 2 (3 a^{2} + a - 2 b) : - 6 a^{2} - 2 a + 4 b

= - 6 a^{2} - 2 a + 4 b + 9 (a + 4 b) + 6 a^{2}

Expand

9 (a + 4 b) : 9 a + 36 b

= - 6 a^{2} - 2 a + 4 b + 9 a + 36 b + 6 a^{2}

= - 6 a^{2} + 6 a^{2} - 2 a + 9 a + 4 b + 36 b

Add similar elements:

- 6 a^{2} + 6 a^{2} = 0

= - 2 a + 9 a + 4 b + 36 b

Add similar elements:

- 2 a + 9 a = 7 a

= 7 a + 4 b + 36 b

Add similar elements:

4 b + 36 b = 40 b

= 7 a + 40 b
