Answer:

x = -
(7)/(4)

Explanation:

given a quadratic in standard form

y = ax² + bx + c ( a ≠ 0 ) , then the equation of the axis of symmetry is

x = -
(b)/(2a)

y = 2x² + 7x - 5 ← is in standard form

with a = 2 and b = 7 , then axis of symmetry is

x = -
(7)/(2(2)) = -
(7)/(4) , that is

x = -
(7)/(4)
