Question 74048
how can i add to understand
5b^3-8b+2b^2 and 3b^2-7b^3+5b
You can only add the coefficients of like terms, terms that have the same exact variables raised to the same exact powers.
{{{(5b^3-8b+2b^2)+(3b^2-7b^3+5b)}}}
{{{5b^3-8b+2b^2+3b^2-7b^3+5b}}}
{{{(5-7)b^3+(2+3)b^2+(-8+5)b}}}
{{{highlight(-2b^3+5b^2-3b)}}}
Happy Calculating!!!!
