In the quadratic formula, −b±b2−4ac√2a, what is b2−4ac called?

Step-by-step explanation:

In the quadratic formula x = -b±√b²-4ac/2a, the expression b²-4ac inside the square root is called the discriminant. The discriminant is the function that determines the nature of the roots of the equation even without the constant a, b and c

If b²-4ac > 0, the roots of the equation will be real and distinct

If b²-4ac < 0 the roots of the equation will be complex number

If b²-4ac = 0 the roots of the equation will be real and the same

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.
