Question

Answer 1

\(a,=5\left(xy-2\right)\\ b,=\left(x-6\right)\left(x+6\right)\\ c,=x^2\left(x-y\right)+4\left(x-y\right)=\left(x^2+4\right)\left(x-y\right)\\ d,=x^2-\left(y-6\right)^2=\left(x-y+6\right)\left(x+y-6\right)\)

Answer 2

a) \(=5\left(xy-2\right)\)

b) \(=\left(x-6\right)\left(x+6\right)\)

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

d) \(=x^2-\left(y^2-12y+36\right)=x^2-\left(y-6\right)^2=\left(x-y+6\right)\left(x+y-6\right)\)

Answer 3

a) \(=5\left(xy-2\right)\)

b) \(=\left(x-6\right)\left(x+6\right)\)

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

d) \(=x^2-\left(y^2-12y+36\right)=x^2-\left(y-6\right)^2=\left(x-y+6\right)\left(x+y-6\right)\)
