Question 209273
4y^2 +25y+25
.
Since  all  signs  are  positive,,all  factor  signs  will  be  positive,,,and  factors  will  add.
.
Factors  of  1st  term,,(4)  are,,,4*1,,,or  2*2
.
factors  of  3rd  term (25)  are,,,25*1 or  5*5
.
Reviewing  all  of  the  combinations  that  add  to  +25, lets  use (4*5 + 1*5)
.
(4y + 5) (y+5)
.
.
check  using  FOIL,,,,4y^2 +20y +5y +25 = 4y^2 +25y+25,,,,ok
