Answer 1

I apologize if it’s not the right anwser but i got it online ( the anwser)

Answer 2

`\tt x_1=\cfrac{9-√(17)}{4}; \ \ x_2=\cfrac{9+√(17)}{4}`

Explanation:

`\displaystyle\tt 2x^2-9x+8=0\\\\x=(-bб √(b^2-4ac))/(2a) \\\\x=(9б√((-9)^2-4\cdot2\cdot8))/(2\cdot2) \\\\x=(9б√(81-64))/(4)\\\\x=(9б√(17))/(4)\\\\x_1=(9- √(17))/(4)\\\\x_2=(9+ √(17))/(4)`
