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

x equals negative five plus or minus the square root of negative five squared minus four times two times eighteen, all divided by two times two

x equals five plus or minus the square root of negative five squared minus four times two times eighteen, all divided by two times two

x equals negative two plus or minus the square root of two squared minus four times negative five times eighteen, all divided by two times negative five

x equals two plus or minus the square root of two squared minus four times negative five times eighteen, all divided by two times negative five

Option 2nd is correct

x equals five plus or minus the square root of negative five squared minus four times two times eighteen, all divided by two times two

Step-by-step explanation:

Given the equation:

Use the quadratic formula:

A quadratic equation .............[1], then the solution is given by:

On comparing given equation with [1]

a = 2 , b = -5 and c = 18

then;

⇒

Therefore, the correct application of the quadratic formula is,

x equals five plus or minus the square root of negative five squared minus four times two times eighteen, all divided by two times two

answer

a the answer hopes this

step-by-step explanation:
