Issolvi y=a(x-4)^2-3

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

Solvi għal a (complex solution)

$$\left\{\begin{matrix}a=\frac{y+3}{\left(x-4\right)^{2}}\text{, }&x\neq 4\\a\in \mathrm{C}\text{, }&y=-3\text{ and }x=4\end{matrix}\right.$$

Passi biex Issolvi l-Ekwazzjoni Lineari

Uża teorema binomjali \left(a-b\right)^{2}=a^{2}-2ab+b^{2} biex tespandi \left(x-4\right)^{2}.

$$y=a\left(x^{2}-8x+16\right)-3$$

Uża l-propjetà distributtiva biex timmultiplika a b'x^{2}-8x+16.

$$y=ax^{2}-8ax+16a-3$$

Ibdel in-naħat sabiex it-termini varjabbli kollha jkunu fuq in-naħa tax-xellug.

$$ax^{2}-8ax+16a-3=y$$

Żid 3 maż-żewġ naħat.

$$ax^{2}-8ax+16a=y+3$$

Ikkombina t-termini kollha li fihom a.

$$\left(x^{2}-8x+16\right)a=y+3$$

Iddividi ż-żewġ naħat b'x^{2}-8x+16.

$$\frac{\left(x^{2}-8x+16\right)a}{x^{2}-8x+16}=\frac{y+3}{x^{2}-8x+16}$$

Meta tiddividi b'x^{2}-8x+16 titneħħa l-multiplikazzjoni b'x^{2}-8x+16.

$$a=\frac{y+3}{x^{2}-8x+16}$$

Iddividi y+3 b'x^{2}-8x+16.

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

Solvi għal a

$$\left\{\begin{matrix}a=\frac{y+3}{\left(x-4\right)^{2}}\text{, }&x\neq 4\\a\in \mathrm{R}\text{, }&y=-3\text{ and }x=4\end{matrix}\right.$$
