__________________________

If we have to find the product then the sign would "×" not "+".

= 3a (5a-6c) × (4a+2c)

= ${15a}^{2}$ - 18ac × 4a + 2c

= ${60a}^{3}$ + ${30a}^{2}c$ ${-72a}^{2}c$ - ${36ac}^{2}$

Answer 2

Answer:

3a(5a-6c) + (4a+2c) (multiply this equation)

15a2 - 18ac + 12a2 + 6ac ( a2 means a square)

28a2 - 12ac (answer)
