Simplify 7b^2-b+3b+6-3b^2+5+2b^2+7b

$7 b^{2} - b + 3 b + 6 - 3 b^{2} + 5 + 2 b^{2} + 7 b$

Step 1

Subtract $3 b^{2}$ from $7 b^{2}$ .

$4 b^{2} - b + 3 b + 6 + 5 + 2 b^{2} + 7 b$

Step 2

Add $4 b^{2}$ and $2 b^{2}$ .

$6 b^{2} - b + 3 b + 6 + 5 + 7 b$

Step 3

Add $- b$ and $3 b$ .

$6 b^{2} + 2 b + 6 + 5 + 7 b$

Step 4

Add $2 b$ and $7 b$ .

$6 b^{2} + 9 b + 6 + 5$

Step 5

Add $6$ and $5$ .

$6 b^{2} + 9 b + 11$
