Question and answer
Evaluate the discriminant of 25x2 + 350x + 49 = 0. Tell how many solutions the equation has and whether the solutions are real or imaginary. A. one real solution B. two imaginary solutions C. two real solutions D. cannot be determined
25x^2 + 350x + 49 = 0 discriminant = b^2 - 4ac = 350^2 - 4(25)(49) = 117600 > 0 therefore, there are two real solutions for the equation 25x^2 + 350x + 49 = 0.
