Question

Expand and combine like terms.
(6y^2+ 5y^4)^2

Answer 1

36y⁴ + 60y⁶ + 25y⁸

Explanation:

(6y² + 5y⁴)² = (6y² + 5y⁴)(6y² + 5y⁴)

we can use the FOIL method to get:

36y⁴ + 30y⁶ + 30y⁶ + 25y⁸

we can simplify the two middle terms and get:

36y⁴ + 60y⁶ + 25y⁸

Answer 2

`\left(6y^2+5y^4\right)^2`

`(6y^2+5y^4)^2=36y^4+60y^6+25y^8`

`=\left(25y^8+60y^6+36y^4\right)`

`=\left(36y^4+60y^6+25y^8\right)`

`=36y^4+60y^6+25y^8`
