Whakaoti mō C
C=4\left(x-3\right)\left(x+4\right)
Whakaoti mō x (complex solution)
x=\frac{-\sqrt{C+49}-1}{2}
x=\frac{\sqrt{C+49}-1}{2}
Whakaoti mō x
x=\frac{-\sqrt{C+49}-1}{2}
x=\frac{\sqrt{C+49}-1}{2}\text{, }C\geq -49
Graph
Tohaina
Kua tāruatia ki te papatopenga
C=4x^{2}+4x+1-49
Whakamahia te ture huarua \left(a+b\right)^{2}=a^{2}+2ab+b^{2} hei whakaroha \left(2x+1\right)^{2}.
C=4x^{2}+4x-48
Tangohia te 49 i te 1, ka -48.
