Answer

Problem

Simplify the expression
\$ (4/a^2+5b+c^2) - (-2/a^2+4b-2c^2) \$

Step

After eleminating the brackets we get

\$ 4/a^2 + 5b + c^2 + 2/a^2 - 4b + 2c^2 \$

Step

Adding like terms together

\$ (4/a^2 + 2/a^2) + (5b - 4b) + (c^2 + 2c^2) \$

Step

Adding like fractions

\$ (4+2)/a^2 + b + 3c^2 \$

Step

After adding we get

\$ 6/a^2 + b + 3c^2 \$
