Hi,

7x²-2x-8=0, so a = 7, b= - 2, and c = -8.

You just need to apply the formula for square equations:

x_{1,2}=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}=\dfrac{-(-2)\pm\sqrt{(-2)^2-4\cdot 7\cdot (-8)}}{2\cdot 7}=\dfrac{2\pm\sqrt{228}}{14}=\dfrac{2\pm\sqrt{4\cdot 57}}{14}=\\\\=\dfrac{1\pm\sqrt{57}}7\Rightarrow x_1=\dfrac{1-\sqrt{57}}7,\;and\;x_2=\dfrac{1+\sqrt{57}}7.

uysha [10]

Answer:

3 30 page printers, 10 70 page printers

Step-by-step explanation:

x + y = 13

40x+70y = 820

Solving for y in first equation gives: y = 13 - x

Plug into second equation: 40x + 70(13 - x) = 820

40x + 910 - 70x = 820

-30 x = -90

x = 3

Plug into original equation: 3 + y = 13

y must = 10.

So, the company owns 3 thirty page presses, and 10 70 page presses,
