Whakaoti mō A
A=5a^{2}+16b
Whakaoti mō a
a=\frac{\sqrt{5\left(A-16b\right)}}{5}
a=-\frac{\sqrt{5\left(A-16b\right)}}{5}\text{, }A\geq 16b
Tohaina
Kua tāruatia ki te papatopenga
A=4a^{2}+12b+a^{2}+4b
Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te a^{2}+3b.
A=5a^{2}+12b+4b
Pahekotia te 4a^{2} me a^{2}, ka 5a^{2}.
A=5a^{2}+16b
Pahekotia te 12b me 4b, ka 16b.
