Using the quadratic formula, plug a=2, b=3, and c=4 into the formula because the equation given can not be factored.

x= -3(+/-) radical (3^2-4*2*2)/2(2)

therefore, x= (-3+ radical 7 i) / 4
x= (-3- radical 7 i )/ 4.

the answer choice is 1.

Answer:

$\displaystyle 2\ \frac{1}{4}$

Step-by-step explanation:

Fractions

They can be expressed as proper fractions, improper fractions or mixed numbers. Proper fractions are such that the numerator is less than the denominator, like 2/5, 7/11, -9/10. Improper fractions are those whose numerators are greater than the denominator, such as 5/3, 10/9, -21/8.

Mixed numbers are expressions made of whole numbers and a proper fraction, like 4 3/5, 1 1/2, -5 4/9. Mixed numbers can be transformed to improper fractions and vice-versa.

The question requires us to find the average change in field position on each run of the running back for the Bulldogs football team which carried the ball 5 times for a total loss of 11 1/4 yards.

The number 11 1/4 is mixed, to express it as an improper fraction, we add the numbers like

$\displaystyle 11+\frac{1}{4}=\frac{45}{4}$
