Find the root of the equation (2y+1)^2 – 4y^2 = 5

Thank you for all the help you can give. My hw is due tonight and I have no idea how to do this... brainliest for the correct and best explained answer.

Respuesta :

Answer:

y = 1

Step-by-step explanation:

Expand (2y + 1)² using FOIL

4y² + 4y + 1 - 4y² = 5

4y + 1 = 5 ( subtract 1 from both sides )

4y = 4 ( divide both sides by 4 )

y = 1 ← root of the equation
