Factorise and divide: (3y^8 - 4y^6 + 5y^4) ÷ y^3
1 answer:
Answer: 3y^4 - 4y^2 + 5
Step-by-step explanation:
Im fairly sure this is the answer but again i dont know
3y^8 = 3 x y x y x y x y x y x y x y x y
4y^6 = 4 x y x y x y x y x y x y
5y^4 = 5 x y x y x y x y
=
<u>(3×y×y×y×y×y×y×y×y)−(4×y×y×y×y×y×y)+(5×y×y×y×y) </u>
y^4
= y^4 [(3×y×y×y×y)−(4×y×y)+(5)]
= 3y^4 - 4y^2 + 5
