Datrys y=-3(x-1)^2-4

$$y = - 3 ( x - 1 ) ^ { 2 } - 4$$

Datrys ar gyfer y

$$y=-3\left(x-1\right)^{2}-4$$

Camau Ateb

Defnyddio'r theorem binomaidd \left(a-b\right)^{2}=a^{2}-2ab+b^{2} i ehangu'r \left(x-1\right)^{2}.

$$y=-3\left(x^{2}-2x+1\right)-4$$

Defnyddio’r briodwedd ddosbarthu i luosi -3 â x^{2}-2x+1.

$$y=-3x^{2}+6x-3-4$$

Tynnu 4 o -3 i gael -7.

$$y=-3x^{2}+6x-7$$

Datrys ar gyfer x (complex solution)

$$x=-\frac{\sqrt{-3y-12}}{3}+1$$

$$x=\frac{\sqrt{-3y-12}}{3}+1$$

Datrys ar gyfer x

$$x=-\frac{\sqrt{-3y-12}}{3}+1$$

$$x=\frac{\sqrt{-3y-12}}{3}+1\text{, }y\leq -4$$
