Answer:
Step-by-step explanation:
f ( x + 1 ) = 3 x ^ { 2 } - 2 x - 5. f ( x + 1) = 3 x 2 − 2 x − 5. Factor the expression by grouping. First, the expression needs to be rewritten as 3x^ {2}+ax+bx-5. To find a and b, set up a system to be solved. Factor the expression by grouping. First, the expression needs to be rewritten as 3 x 2 + a x + b x − 5.
