Example

3(r+2s)=2t-4
a⋅(b-2)=3b
3(r+2s)=2t-4
a⋅(b-2)=3b

Question

$$(2a^{2}-2b^{2}+Bc^{3})+(2a^{2}+4b^{2}-5c^{3})-; (a^{2}+b^{2}+c^{3})$$

Answer

$$2*a^2-2*b^2+Bc^3+2*a^2+4*b^2-5*c^3-;a^2+b^2+c^3$$

Solution


Remove parentheses.
\[\begin{aligned}&2{a}^{2}-2{b}^{2}+{Bc}^{3}+2{a}^{2}+4{b}^{2}-5{c}^{3}-\\&{a}^{2}+{b}^{2}+{c}^{3}\end{aligned}\]
