$(5 b^{2} + 3 b) + (b^{2} - 2 b)$ $(5b^2 + 3b) + (b^2 - 2b)$

Grouping like terms:

$= (5 b^{2} + b^{2}) + (3 b - 2 b)$ $= color(red)((5b^2+b^2)) + color(blue)((3b-2b))$

$= 6 b^{2} + b$ $= color(red)(6b^2) + color(blue)(b)$

How do you simplify (5b^2 + 3b) + (b^2 - 2b)(5b2+3b)+(b2−2b)(5b^2 + 3b) + (b^2 - 2b)?
