Question

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

Answer 1

Answer:

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

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

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

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

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

have a great day!!

Answer 2

Answer:

36y⁴ + 60y⁶ + 25y⁸

Step-by-step 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
