\frac{4b\times 5b}{\left(2b+1\right)\left(a+1\right)}
Iddividi \frac{4b}{2b+1} b'\frac{a+1}{5b} billi timmultiplika \frac{4b}{2b+1} bir-reċiproku ta' \frac{a+1}{5b}.
\frac{4b^{2}\times 5}{\left(2b+1\right)\left(a+1\right)}
Immultiplika b u b biex tikseb b^{2}.
\frac{20b^{2}}{\left(2b+1\right)\left(a+1\right)}
Immultiplika 4 u 5 biex tikseb 20.
\frac{20b^{2}}{2ba+2b+a+1}
Applika l-propjetà distributtiva billi timmultiplika kull terminu ta' 2b+1 b'kull terminu ta' a+1.
\frac{4b\times 5b}{\left(2b+1\right)\left(a+1\right)}
Iddividi \frac{4b}{2b+1} b'\frac{a+1}{5b} billi timmultiplika \frac{4b}{2b+1} bir-reċiproku ta' \frac{a+1}{5b}.
\frac{4b^{2}\times 5}{\left(2b+1\right)\left(a+1\right)}
Immultiplika b u b biex tikseb b^{2}.
\frac{20b^{2}}{\left(2b+1\right)\left(a+1\right)}
Immultiplika 4 u 5 biex tikseb 20.
\frac{20b^{2}}{2ba+2b+a+1}
Applika l-propjetà distributtiva billi timmultiplika kull terminu ta' 2b+1 b'kull terminu ta' a+1.
