Answer:
Step-by-step explanation:
Were there not several equations from which to choose?
The coefficients of 25x^2 - 10x + 4 are {25, -10, 4}. The discriminant is thus b^2 - 4ac, or (-10)^2 - 4(25)(4), or 100 - 400, or -300. Because the discriminant is negative, the quadratic has no real solutions.
