Answer 1

a) 2x²+4y =
2.(x² + 2y)


b) ab² - 8ac=
a.(b² - 8c)


c) 12xy² + 9x⁵y³
3xy².(4 + 3x⁴y)


d) 4ab²c⁵-6ab³+14b²c
2b².(2ac⁵ - 3ab + 7c)


e) 6x²y³-2x^5y^6-4x²y²=
2x²y².(3y - x³y⁴ - 2)

f)2x²+2xy-3x-3y=
2x.(x + y) - 3(x + y)
(2x - 3) .(x + y)


g)2+2y+x+xy=
2.(1+y) + x.(1+y)
(2+x) + (1 +y)


h)2x²+2xy-3x-3y=
2x.(x + y) - 3(x + y)
(2x - 3) .(x + y)


i)ax+b³y+ay+b³x
ax + ay + b³y + b³x
a.(x + y) + b³.(y + x) 
(a + b³).(x + y)


j)4x³y-x^5-4xy³+y²x³=
x³.(4y - x²) - xy².(4y + x²)
(x³ - xy²).(4y - x²)



k)x²-10xy+25y²=
(x - 5).(x- 5)



l)36c²-12cb+b²=
(6c + b).(6c + b)



m)49x²-56xy+16y²=
(7x - 4y).(7x - 4y)



n)81x^4-90x²y^4+25^8=
(9x² - 5y⁴).(9x² - 5y⁴)



o)16/9d²+8/5db²+9/25b^4
(4/3d + 3/5b²).(4/3d + 3/5b²)
