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.
