Simplify (6a-2b^2-a)+(b-3+9a^2)

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

Step 1

Remove parentheses.

$6 a - 2 b^{2} - a + b - 3 + 9 a^{2}$

Step 2

Subtract $a$ from $6 a$ .

$- 2 b^{2} + 5 a + b - 3 + 9 a^{2}$

Step 3

Simplify the expression.

Move $- 3$ .

$- 2 b^{2} + 5 a + b + 9 a^{2} - 3$

Move $b$ .

$- 2 b^{2} + 5 a + 9 a^{2} + b - 3$

Move $5 a$ .

$- 2 b^{2} + 9 a^{2} + 5 a + b - 3$

Reorder $- 2 b^{2}$ and $9 a^{2}$ .

$9 a^{2} - 2 b^{2} + 5 a + b - 3$

$9 a^{2} - 2 b^{2} + 5 a + b - 3$
