$$\displaystyle \left( p+q \right) -\left( p-q \right) $$ is equal to

$$\displaystyle { a }^{ 2 }-\left( -{ a }^{ 2 } \right) $$ is equal to

Subtract the sum of $$\displaystyle { 9b }^{ 2 }+{ 3c }^{ 2 }$$ and $$\displaystyle { 2b }^{ 2 }+bc+{ 2c }^{ 2 }$$ from the sum of $$\displaystyle { 2b }^{ 2 }-2bc-{ c }^{ 2 }$$ and $$\displaystyle { c }^{ 2 }+2bc-{ b }^{ 2 }$$.

$$\displaystyle 4x-\left( -2y+5x \right) $$ is equal to

Simplify: $$\displaystyle \left( { a }^{ 3 }-{ 2a }^{ 2 }+4a-5 \right) -\left( -{ a }^{ 3 }-8a+{ 2a }^{ 2 }+5 \right) $$

If we take away $$\displaystyle -8abc$$ from $$\displaystyle -7abc$$, then the result is equal to

What should be subtracted from $$\displaystyle { x }^{ 2 }-4xy-{ y }^{ 2 }$$ to get $$1$$?

What is the sum of $$\displaystyle \left( 4a+5b \right) ,\left( -6a+2b \right) ,\left( 7a-6b \right) $$?

Simplify: $$(a^4-3a^2 + 6a - 8) - (a^4 - 10a + 4a^2 + 8)$$

By how much is $$\displaystyle a^{4}+4a^{2}b^{2}+b^{4}$$ more than $$\displaystyle a^{4}-8a^{2}b^{2}+b^{4}$$ ?
