Question

Answer 1

\(a,=5\left(4x-y\right)\\ b,=2x\left(x-1\right)\\ c,=\left(x-6\right)\left(x+y\right)\\ e,=2xy\left(2x-4y+5xy\right)\\ g,=4x^2\left(5xy-3x\right)\\ h,=4x^2\left(2x^2+3y^4-4xy^4\right)\)

Answer 2

a) \(20x-5y=5\left(4x-y\right)\)

b) \(5x\left(x-1\right)-3x\left(x-1\right)=x\left(x-1\right)\left(5-3\right)=2x\left(x-1\right)\)

c) \(x\left(x+y\right)-6x-6y=x\left(x+y\right)-6\left(x+y\right)=\left(x+y\right)\left(x-6\right)\)

e) \(4x^2y-8xy^2+10x^2y^2=2xy\left(2x-4y+5xy\right)\)

g) \(20x^2y-12x^3=4x^2\left(5y-3x\right)\)

h) \(8x^4+12x^2y^4-16x^3y^4=4x^2\left(2x^2+3y^4-4xy^4\right)\)
