6x^2 - 8 = 4x^2 + 7x
6x^2 - 4x^2 - 7x - 8 = 0
2x^2 - 7x - 8 = 0
discriminant = b^2 - 4ac; where a = 2, b = -7 and c = -8
d = (-7)^2 - 4(2)(-8)
d = 49 + 64
d = 113
the discriminant is greater than zero, so there are two real roots

Answer:
1,417,000
Step-by-step explanation:
Given that:
Score = 1,475,623
96% of nationwide
96% of score gives the best estimate of the number of scores below 720
0.96 * 1475623
= 1416598.08
The best estimate is 1,417,000
A must be equal to b or be a multiple of b or -b in order to be an integer
example 5/5 is an integer (1)
60/5 is an integer (12) because 60 is a multiple of 5
-30/5 is an integer (-6) because -30 is a multiple of -5
