Step-by-step explanation:
Given: Factories the expression (y² + 7y + 10)÷(y + 5)
Sol. Given expression
(y² + 7y + 10)÷(y + 5)
Factor the expression that are not already factored.
→ [(y + 2)(y + 5)]/ (y + 5)
Cancel out y + 5 in both numerator and denomination.
→ y + 2 Ans.
Given: Factories 10y(6y + 21) ÷ 5(2y + 7)
Sol. The given expression
10y(6y + 21) ÷ 5(2y + 7)
Use the distribution property to multiply 10y by 6y + 21.
→ [(60y² + 210y)/5] (2y + 7)
Express 60y² + 210y(2y + 7) as a single fraction.
→ [(60y² + 210y)(2y + 7)] / 5
Apply the distribution property to multiplying each term of 60y² + 210y by each term of 2y + 7.
→ (120y³ + 420y² + 420y² + 1470y) / 5
Combine 420y² and 420y² to get 840y².
→ 120y³ + 840y² + 1470y
→ 6y(2y + 7)² Ans.
