Steps Problem Solution

1

Simplify the expressions by using addtion

\$ (-x^2-y^2-5xy)+(3x^2-3y^2+4xy) \$

2

Given expressions

\$ (-x^2-y^2-5xy)+(3x^2-3y^2+4xy) \$

3

After eleminating the brackets we get

\$ -x^2-y^2-5xy + 3x^2-3y^2+4xy \$

4

Grouping like terms together

\$ -x^2+3x^2-y^2-3y^2-5xy+4xy \$

5

After simplification we get

\$ 2x^2-4y^2-xy \$

6

Hence the solution of the given expressions are

\$ 2x^2-4y^2-xy \$
