Question

Which values of c will cause the quadratic equation –x2 + 3x + c = 0 to have no real number solutions? Check all that apply.

A. –5
B. -9/2
C. -1/4
D. 1
E. 9/4

Answer 1

Answer:

for a quadratic equation to have no real roots, then D < 0

here a = -1 , b = 3 and c = c

D = b^2 - 4ac = (3)^2 - 4*(-1) * c < 0

9 + 4c < 0

4c < -9

c < -9/4 or c < - 2.25

option B -9/2
