Solve the inequality c - 12 > -16.
Plot the solution on the number line.
Answer:
-2,3 and \frac{-1±i\sqrt{3} }{2}
Step-by-step explanation:
Given is an equation of power 4 in polynomial as
We have to find the zeroes of the funciton
By rational roots theorem since constant term = -6 and Leading coefficient =1
possible rational factors can be
±1,±2,±3,±6
By trial and error we try one by one.
So x=3 is zero and x-3 is factor
Try with -2
x=-2 is the zero
Now divide the given polynomial by (x+2)(x-3) to get quadratic form
Given polynomial =
Find the roots of quadratic by formula
x=
So roots are -2,3 and \frac{-1±i\sqrt{3} }{2}
