Answer:

Step-by-step explanation:

Rewrite this equation in standard quadratic form:  x^2 + 13x + 4 = 0.

Here the coefficients are 1, 13 and 4, so the discriminant is

b^2-4ac, or 169 - 4(1)(4) = 153

Since the discriminant is + there are two real, unequal roots.  They are:

       -13 ± √153

x =  ------------------

            2

x = ----------------
