Answer:
x = (-7 ±√89)/4 . . . . . the inverse of selection 3.)
Step-by-step explanation:
You have a quadratic ax²+bx+c=0 with a=2, b=7, c=-5. The solution is given by the quadratic formula as ...
... x = (-b ±√(b² -4ac))/(2a)
Putting your values into the formula gives ...
... x = (-7 ±√(7²-4(2)(-5)))/(2(2))
... x = (-7 ±√89)/4
