I s x + 4 a x 5 - 6 x 4 - 2 x 3 - 7 x 2 + 5 x + 2564

I s x + 20 a x - 39 x + 2564

خطوات الحلّ

I s x + 4 a x \cdot 5 - 6 x \cdot 4 - 2 x \cdot 3 - 7 x \cdot 2 + 5 x + 2564

4 a x \cdot 5 = 20 a x

6 x \cdot 4 = 24 x

2 x \cdot 3 = 6 x

7 x \cdot 2 = 14 x

= I s x + 20 a x - 24 x - 6 x - 14 x + 5 x + 2564

- 24 x - 6 x - 14 x + 5 x = - 39 x :

= I s x + 20 a x - 39 x + 2564

x = (7100) (1 + \frac{0.065}{52})^{260}

(x + 4) (x - 12) = 0

6 x - 11 = 2 x + 9

(x - 1) (x + 5) = - 8
