Brainlies asap! part a: factor 3x²y² − xy² − 2y². show your work. (4 points) part b: factor x² + 6x + 9. show your work. (3 points) part c: factor x² − 25. show your work. (3 points)

Part A:
3x²y²-xy²-2y²
(3x²+2x)+(-3x-2)
x(3x+2)-(3x+2)
(3x+2)(x-1)
y²(x-1)(3x+2)

Part B:
x²+6x+9
(x²+3x)+(3x+9)
x(x+3)+3(x+3)
(x+3)(x+3)
(x+3)²

Part C:
x²-25
x²-5²
apply difference of squares rule: x²-y²=(x+y)(x-y)
x²-5²=(x+5)(x-5)
(x+5)(x-5)

I hope this helps
