Factor completely. If a polynomial is prime, state this

20y^2 - 25y + 5 =
5(4y^2 - 5y + 1) =
5(4y - 1)(y - 1)

20y^2 - 25y + 5

common factor of 5...

5(4y^2 - 5y + 1) = 5[4y^2 - 4y - y + 1] = 5[4y(y - 1) - (y - 1)] = 5(y - 1)(4y - 1)

check

¶

5 (-1 + y) (-1 + 4 y)

5(4y^2-5y+1)

5*(4y - 1)*(y - 1)
