Issolvi f(x)=-0.02x^2+1.4x+5.7,w

$$f ( x ) = - 0.02 x ^ { 2 } + 1.4 x + 5.7 , w$$

Solvi għal f

$$f=-\frac{x}{50}+1.4+\frac{57}{10x}$$

$$x\neq 0$$

Passi biex Issolvi l-Ekwazzjoni Lineari

L-ekwazzjoni hija f'forma standard.

$$xf=-\frac{x^{2}}{50}+\frac{7x}{5}+5.7$$

Iddividi ż-żewġ naħat b'x.

$$\frac{xf}{x}=\frac{-\frac{x^{2}}{50}+\frac{7x}{5}+5.7}{x}$$

Meta tiddividi b'x titneħħa l-multiplikazzjoni b'x.

$$f=\frac{-\frac{x^{2}}{50}+\frac{7x}{5}+5.7}{x}$$

Iddividi -\frac{x^{2}}{50}+\frac{7x}{5}+5.7 b'x.

$$f=-\frac{x}{50}+\frac{7}{5}+\frac{57}{10x}$$

Solvi għal x

$$x=25\sqrt{f^{2}-\frac{14f}{5}+2.416}-25f+35$$

$$x=-25\sqrt{f^{2}-\frac{14f}{5}+2.416}-25f+35$$
