For the equation y = 2x2 - 5x + 18, choose the correct
application of the quadratic formula.

Option (2)

Step-by-step explanation:

For a quadratic equation,

ax² + bx + c = 0

roots of this equation can be determined by using quadratic formula,

x =

Comparing this quadratic equation with the given equation,

y = 2x² - 5x + 18 = 0

a = 2

b = (-5)

c = 18

By substituting these values in the given formula,

x =

Therefore, Option (2) will be the answer.

part a: 1.08

part b: 27.59

(8+64)^2= 5184 < answer

step-by-step explanation:

2^3 = 8

4^3= 64

(8+64)^2 = 5184
