Answer: y=3/4x+3
Step-by-step explanation:
Answer:
Step-by-step explanation:
a=3, b=-15, c=20
Discriminant can be calculated as
The roots are imaginary
The solution is
The roots are not real i.e these are imaginary
a=3, b=5, c=-8
Discriminant can be calculated as
The roots are real
By quadratic formula method
The solution is
which are required roots.
I choose this method because I can get the solutions directly by substituting the values in formula, and I don't have to guess the possible solutions.
Answer:
Step-by-step explanation:
Given
Required
Find n
Simplify (n + 1)!
Factorize
Divide both sides by n!
Open brackets
Collect like terms
Multiply both sides by -1
