Answer 1

Answer:

6y^2+2y

Step by step explanation:

2y*(y+3)+4y*(y-1)

Distribute 2y through the parentheses

2y^2+6y+4y*(y-1)

Distribute 4y through the parentheses

2y^2+6y+4y^2-4y

Collect like terms

6y^2+6y-4y

Collect like terms

6y^2+2y

Answer

6y^2+2y

Answer 2

6y² + 2y

Explanation:

Use distributive property:a*(b+c) =a*b + a*c

2y(y + 3) + 4y(y -1) =2y*y + 2y*3 + 4y*y - 4y*1

= 2y² + 6y + 4y² - 4y

= 2y² + 4y² + 6y - 4y {Combine like terms}

= 6y² + 2y
