Pls answer i need it now
Express each trinomial as a product
1) 9x² - 12x + 4
2) 16x² + 24xy + 9y²
3) 36x² - 60xy + 25y²
4) 4a² - 12ac + 9c²
Pls show the solution thx

Answer:
1.(3x-2) (3x-2)
(3x)x(3x)=9x²
(3x)x(-2x)=-6x
(3x)x(-2x)=-6x
-6x+-6x =-12x
(-2)x(-2)=+4
2.(4x+3y)(4x3y)
(4x)x(4x)=16x²
(4x)x(3y)=12xy
(4x)x(3y)=12xy
12xy+12xy=24xy
(3y)x(3y)=9y²
3.(6x+5y)(6x-5y)
(6x)x(6x)=36x²
(6x)x(-5y)=30xy
(6x)x(-5y)=30xy
30xy+30xy=60xy
(5y)x(-5y)=25y²
4.(2a+3c)(2a-3c)
(2a)x(2a)=2a²
(2a)x(-3c)=-6ac
(2a)x(-3c)=-6ac
-6ac+-6ac=-12ac
(3c)x(3c)=9c²
