Answer:

$4 {x}^{2} - 2x + x = 5 {x}^{2} + 2x \\ 4 {x}^{2} - x = 5 {x}^{2} + 2x \\ 4 {x}^{2} - 5 {x}^{2} = 2x + x \\ - 1 {x}^{2} = 3x \\ - x = 3 \\ x = - 3 \\ thank \: you$

Answer:

$\large\boxed{x=-\dfrac{7-\sqrt{97}}{4}\ \vee\ x=-\dfrac{7+\sqrt{97}}{4}}$

Step-by-step explanation:

$ax^2+bx+c=0\\\\\Delta=b^2-4ac\\\\\text{if}\ \Delta0,\ \text{then an equation has two solutions:}\ x=\dfrac{-b\pm\sqrt\Delta}{2a}\\\\\text{We have:}\\\\-2x^2-7x+10=4\qquad\text{subtract 4 from both sides}\\\\-2x^2-7x+6=0$

$a=-2,\ b=-7,\ c=6\\\\\Delta=(-7)^2-4(-2)(6)=49+48=97>0\\\\\sqrt\Delta=\sqrt{97}\\\\x=\dfrac{-(-7)\pm\sqrt{97}}{2(-2)}=\dfrac{7\pm\sqrt{97}}{-4}=-\dfrac{7\pm\sqrt{97}}{4}$

Answer:

4/5 acre

Step-by-step explanation:

We assume your allocations are ...

goats: 3/5 acre

pigs: 1/5 acre

llamas: 2/5 acre

2 acres is 10/5 acres, so the remaining area is ...

10/5 -3/5 -1/5 -2/5 = (10 -3 -1 -2)/5 = 4/5

4/5 acre is allocated to horses.
