How do you factor #6r + 8- r + 8r + 9r ^ { 2} + 3#?
#6r+8-r+8r+9r^2+3#
#= 9r^2+13r+11#
#= 9(r+13/18+sqrt(227)/18i)(r+13/18-sqrt(227)/18i)#
Given:
First rearrange into standard form, in decreasing order of degree, combining terms of the same degree:
Now this is in standard form:
If you want to factor it with Complex coefficients then you can do so with the help of the quadratic formula.
Hence, two factors of our quadratic can be written:

To factor the expression 6r + 8 - r + 8r + 9r^2 + 3:
Group the like terms: = (6r - r + 8r) + (8 + 9r^2 + 3)
Combine the like terms within each group: = (13r + 8r^2) + (11 + 9r^2)
The expression is now factored as much as possible.
