Question

Grouping 12x3 – 9x2 + 4x - 3?

Answer 1

Answer:4x+15

Step-by-step explanation: PEMDAS. First you multiply 12x3 and 9x2 so you get 36-18. Then you subtract 18 from 36 leaving you with 18. Then you combine 18 and -3, leaving you with 4x-15.

Answer 2

`12x^(3) - {9x}^(2) + 4x - 3 = \\ = 3 {x}^(2) (4x - 3) + 1(4x - 3) = \\ = (4x - 3)( {3x}^(2) + 1)`
