Answer:
Option 2 is correct that is 
and 
and 
Step-by-step explanation:
We have been given with the expression 
We will simplify the given expression by factorisation we will get 
Taking x as common from first two terms in numerator and 2 from last two terms in numerator
Similarly, take x common from first two terms and 9 from last two terms in denominator we will get
After arranging the terms we will get 
Taking out the common factor which is (x-12) from numerator and denominator it will get cancelled we will get
Hence, Option 2 is correct that is and and
Answer is -7/2
Gradient or slope is found by change in y over change in x.
Or
(y2 - y1) over (x2 - x1)
So
(-2 -5) over (4-2)
= -7/2
Answer:
Step-by-step explanation:
Given
Required
Determine the type of roots
Represent Discriminant with D; such that
D is calculated as thus
And it has the following sequence of results
When 
then the roots of the quadratic equation are real but not equal
When 
then the roots of the quadratic equation are real and equal
When 
then the roots of the quadratic equation are complex or imaginary
Given that ; This means that and base on the above analysis, we can conclude that the roots of the quadratic equation are complex or imaginary
