Answer:

two real, equal roots

Step-by-step explanation:

Start by finding the discriminant, b^2 - 4ac.  The coefficients of this quadratic are a = 49, b = 42 and c = 9.  The discriminant is therefore

(42)^2 - 4(49)(9) = 0.  Rule:  If the discriminant is zero (0), then the quadratic has two real, equal roots.
