Sagot :

The subtractiion we are asked to carry out is

[tex](-10m^2-11mw-7w^2)-(-4m^2+5mw-12w^2)[/tex]

In subtracting the expression given we first get rid of the parenthesis by writing out the subtraction as

[tex]-10m^2-11mw-7w^2+4m^2-5mw+12w^2[/tex]

now we combine the like terms to get

[tex](-10m^2+4m^2)+(-11mw-5mw\text{)}+(-7w^2+12w^2)[/tex]

simplifying the above gives

[tex]-6m^2-16mw+5w^2[/tex]

which is our answer!
