sorry, if its wrong
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
we have
Group terms that contain the same variable, and move the constant to the opposite side of the equation
Combine like terms
Divide by 
both sides
therefore
<u>the answer is</u>
the value of p in the linear equation is
