Identify the terms in the polynomial: \(-3x^4 + 12x^3 - 18x^2\).
Determine the greatest common factor (GCF) of the coefficients: \(-3, 12,\) and \(-18\). The GCF is \(3\).
Identify the smallest power of \(x\) in the polynomial terms, which is \(x^2\).
Factor out the GCF \(3x^2\) from each term in the polynomial: \(-3x^4, 12x^3,\) and \(-18x^2\).
Rewrite the polynomial as \(3x^2(-x^2 + 4x - 6)\) after factoring out the GCF.
