Explanation:

We need to solve the given quadratic equations.

1.

$x^2=-5x+2\\\\x^2+5x-2=0$

Using the formula to find solutions.

We have, a = 1, b = 5 and c = -2

So,

$x=(-5\pm √(5^2-4(1)(-2)) )/(2)\\\\x=0.37,-5.37$

2.

$x^2+4x+17=8-2x\\\\x^2+4x+17-8+2x=0\\\\x^2+6x+9=0$

We have,

a = 1, b = 6 and c = 9

$x=(-6\pm √(6^2-4(1)(9)) )/(2)\\\\x=-3,-3$

Hence, this is the required solution.
