The quadratic formula is x equals negative b plus or minus the square root of b squared minus four times a times c, all over 2a. 
Looking at the equation, we can find the values for a, b, and c
a=7
b= -10
c= -2

So then putting that back into standard form, which is ax^2+bx+c, we know Haley's function in standard form is 7x^2-10x-2

The required quadratic function will be 7x^2 -10x + 2 = 0

Quadratic expression

The standard quadratic equation is given as

ax^2 + bx + c = 0

where b and c are the coefficients used in finding the zeros of the equation

The general formula

x = -b±√b²-4ac/2a

Given the equation

x = -(-10)±√(-10)²-4(7)(-2)/2(7)

Comapring, we will have:

a = 7, b = -10 and c = 2

The required quadratic function will be 7x^2 -10x + 2 = 0
