Question
_______ is a factor of 4x2 - 9x + 5.
- x - 10
- x - 4
- x - 1
- x - 3
The correct answer is: x - 1
4x2 -9x +5
= 4x2 -4x -5x +5
= 4x(x-1) -5(x-1)
= (4x -5)(x-1)
(x-1) is a factor of 4x2 - 9x + 5.
4x2 -9x +5
= 4x2 -4x -5x +5
= 4x(x-1) -5(x-1)
= (4x -5)(x-1)
(x-1) is a factor of 4x2 - 9x + 5.
