distance (-1,0),(2,1)

الحلّ

distance

(- 1, 0), (2, 1)

10

خطوات الحلّ

(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2}

(x_{1}, y_{1}), (x_{2}, y_{2})

احسب البعد بينهو

(2, 1)

(- 1, 0)

البعد بين

= (2 - (- 1))^{2} + (1 - 0)^{2}

بسّط

= 10

\frac{3 x ^{2} - 18 x + 24}{x ^{2} - 4 x}

\frac{x}{x - 4}

f (x) = x^{2} + 2 x - 3

f (x) = \frac{( x - 4 )}{3}
