Answer:
b ) One factor ( 4x - 3).
Step-by-step explanation:
Given : 4x² + 5x − 6.
To find : Find factors.
Solution : We have given
4x² + 5x − 6.
On factoring
4x² + 8x - 3x − 6.
Taking common 4x from first two term and -3 from last two terms.
4x ( x + 2) - 3 ( x + 2)
On grouping
( 4x -3) ( x + 2).
Factors ( 4x -3) ( x + 2).
Therefore, b ) One factor ( 4x - 3).
