Answer:
2 reals and 2 rationals.
Step-by-step explanation:
The discriminate gives
b^2 - 4*a*c
b = -7
a = 5
c = 2
(-7)^2 - 4(5)(2)
49 - 40
9
Taking the square root gives you +/-3
The discriminate tells you that there are 2 roots, both real and both rational
x = [(-7) +/- 3 ]/2*5
x = (- 7 - 3)/10 = - 1
x = (- 7 + 3)/10 = -0.4

This is because the numbers are increasing.
M = Gradient M = 1/1 = 1
