Question

Which of the following is the complete factorization of 10x - 3 - 3x2?



(3x - 1)(x + 3)
-(3x + 1)(x - 3 )***********
-(3x - 1)(x - 3)
I think it is the one with ********

Answer 1

i think you're incorrect..

Answer 2

\[-3x^2+ 10x - 3 = -3x^2 + x + 9x - 3 = -x(3x -1) + 3(3x - 1) \\ = (-x + 3)(3x - 1) = \cdots\]

Answer 3

your choice would have + 3 as the constant when you distribute

Answer 4

\[=-1 \times (x -3) \times (3x - 1) = \cdots\]
