Answer:
2(x^2)-1
Step-by-step explanation:
The square of a number is just the number squared. We don't know what the number is so I will just say it is x. So we have 2 times x^2. Then we have to minus 1 from that. So 2(x^2)-1.
Hope this helps! :D

Answer:
(fg)(x) = 12x^3 + 9x^2 + 28x + 21
Third option
Step-by-step explanation:
(fg)(x) = (3x^2 + 7)(4x + 3)
(fg)(x) = = (3x^2)(4x) + (3x^2)(3) + (7)(4x) + (7)(3)
(fg)(x) = 12x^3 + 9x^2 + 28x + 21
