`a, P = 2x(3 - x^2)`
`b, Q = 5x^2(x-3y)`
`c, R = xy(3x^2y^2 - 6y^2z + 1)`
a) \(P=6x-2x^3\)
\(P=2x\left(3+x^2\right)\)
b) \(Q=5x^3-15x^2y\)
\(Q=5x^2\left(x-3y\right)\)
c) \(R=3x^3y^3-6xy^3z+xy\)
\(R=xy\left(3x^2y^2-6y^2z+1\right)\)
a,P=2x(3−x2)𝑎,𝑃=2𝑥(3-𝑥2)
b,Q=5x2(x−3y)𝑏,𝑄=5𝑥2(𝑥-3𝑦)
c,R=xy(3x2y2−6y2z+1)
