Answer 1

help?

Answer 2

-4.8 and 3.5
?

Answer 3

\[x^2+4x-\frac{35}{10}\text{ = }0 \]The following are exact symbolic solutions to the above equation.\[\left\{x\to \frac{1}{2} \left(-4-\sqrt{30}\right),x\to \frac{1}{2} \left(-4+\sqrt{30}\right)\right\} \]\[\{x\to -4.73861,x\to 0.738613\} \]

Answer 4

no real soultions?

Answer 5
