Answer:
[tex]36x^{2} +60x +25[/tex]
[tex]16x^{2} +48x +36[/tex]
Step-by-step explanation:
If you factor the first one you get [tex](6x + 5)^2[/tex]
The 6x times 5 gives 30x, added to 30x, the middle term so it works.
For the 2nd one you know the factoring has to be [tex](4x + 6)^{2}[/tex] so its easy to multiply to get 48x as the middle term.
