Answer:
8ax + (4a²- 6a)
Step-by-step explanation:
g(x)=4x²−6x
g(x+a)
= 4(x+a)² - 6(x+a)
= 4( x² + 2ax + a²) - 6x - 6a
= 4x² + (4)2ax + (4)a² - 6x - 6a
= 4x² + 8ax + 4a² - 6x - 6a
= 4x² + 8ax - 6x + 4a²- 6a
= 4x² + (8a - 6)x + (4a²- 6a)
g(x+a) - g(x)
= [4x² + (8a - 6)x + (4a²- 6a)] - (4x²−6x)
= 4x² + (8a - 6)x + (4a²- 6a) - 4x² + 6x
= (8a - 6)x + (4a²- 6a) + 6x
= (8a - 6 + 6)x + (4a²- 6a)
= 8ax + (4a²- 6a)
