Question

Answer 1

1) \(-3x^2y^3-6x^3y^2-x^2y^2=-x^2y^2\left(3y+6x+1\right)\)

2) \(5x^2y^4-10x^4y^2+5x^2y^2=5x^2y^2\left(y^2-2x^2+1\right)\)

3) \(-2x^3y^4-4x^4y^3-21y^3=-y^3\left(2x^3y+4x^4+21\right)\)

4) \(4x^3y^2-8x^2y^3+12x^4=4x^2\left(xy^2-2y^3+3x^2\right)\)

Answer 2

5) -7x²y⁵-14x³y⁴-21y³ = -7y³(x²y²+2x³y+3)

6) -8x³y+16xy²-24=8(-x³y+2xy²-3)

7) 12x³y-6xy+3x = 3x(4x²y-2y+1)
