Answer:
(5x + 4)(3x+2)
Step-by-step explanation:
15x² + 22x + 8
First, you find two, when added equals 22 and when multiplied together equals 15*8
You then replace 22x with the two numbers
15x² + 10x + 12x + 8
You then group the above expression in 2s
(15x²+10x) + (12x + 8)
Find common factors in each group
5x(3x + 2) + 4(3x + 2)
(5x + 4)(3x+2)
