The diagram represents the factorization of x squared minus 9 x plus 18 It is partially completed. x negative 3 x x squared ? negative 6 ? 18 Which two terms are missing from the diagram?

Answer
A
negative 3 x and negative 6 x
B
negative x and negative 8 x
C
negative 4 x and negative 5 x
D
negative 2 x and negative 7 x

Explanation

The trinomial factors as (x − 3)(x − 6), since 3 × 6 = 18 and −3 + −6 = −9. Multiplying the factors gives x² − 6x − 3x + 18, so the missing terms are −3x and −6x. That is choice C.
