Answer:

2 complex conjugates

Step-by-step explanation:

The discriminate is the part of the quadratic formula that is under the radical sign.  If the discriminate is negative, that means that the solutions, both of them, are complex conjugates, aka imaginary solutions.

For this case we have that by definition, the discriminant of an equation is given by:

D = b ^ 2-4 (a) (c)

We have the following cases:

D> 0: Two different real roots

D = 0:Two equal real roots

D Two different complex roots

In this case we have to:

D = -6, -6 , Then we have two different complex roots.

Alex

Answer:

252 bags of maize

Step-by-step explanation:

From the question, we are told that a farmer harvested maize

In the year 2012 = 144 bags of maize

In the year 2013(following year) the harvest decreased in the ratio 3:4

This means

3:4 = 2013: 2012.

Where number of bags harvested in 2013 = unknown = x

3/4 = x/ 144

Cross multiply 4x = 3 × 144

x = 3 × 144/ 4

× = 108

This means 108 bags of maize was harvested in 2013

The total number of bags harvested is = 108 + 144

= 252 bags of maize.
