Question 1 Report
The factors of 9 - (x2 - 3x - 1)2 are
-(x - 4)(x + 1) (x - 1)(x - 2)
(x - 4)(x - 2) (x - 1)(x + 1)
-(x - 2)(x + 1) (x - 2) (x - 1)
(x - 2)(x + 2) (x - 1)(x + 1)
Answer Details
9 - (x2 - 3x - 1)2 = [3 - (x2 - 3x - 1)] [3 + (x2 - 3x - 1)]= (3 - x2 + 3x + 1)(3 + x2 - 3x - 1)= (4 + 3x - x2)(x2 - 3x + 2)= (4 - x)(1 + x)(x - 1)(x - 2)= -(x - 4)(x + 1) (x - 1)(x - 2)
