Answer 2

Answer:

= 16a² − 12ab + 20ac + 12a − 9b + 15c

Step-by-step explanation:

(4a−3b+5c) (4a+3)

1) KFC rule for subtraction

= (4a + −3b +5c) (4a+3)

2) Regroup and multiply

= (4a)(4a)  +(4a)(3) + (−3b)(4a) + (−3b)(3) + (5c)(4a) + (5c)(3)

3) Answer

= 16a² + 12a − 12ab − 9b + 20ac +15c

= 16a² − 12ab + 20ac + 12a − 9b + 15c
