Answer:

Factoring out Greatest Common Factor (GCF)


6xy+12x^2y^2-4x^3y^3

Factor out greatest common term
2xy:


\implies 2xy(3+6xy-2x^2y^2)

Factoring by Grouping


20x^2+11x-3


\implies a=20, b=11, c=-3


\implies ac=20 \cdot -3=-60

Find 2 two numbers that multiply to ac (-60) and sum to b (11)

Factors of 60: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60

Therefore, the two numbers are 15 and -4

Rewrite b as the sum of these 2 numbers:


\implies 20x^2+15x-4x-3

Factorize the first two terms and the last two terms separately:


\implies 5x(4x+3)-1(4x+3)

Factor out the common term (4x + 3):


\implies (5x-1)(4x+3)

Factoring by Grouping


3x^2+3xa-2x-2a

Factorize the first two terms and the last two terms separately:


\implies 3x(x+a)-2(x+a)

Factor out the common term (x + a):


\implies (3x-2)(x+a)
