Factoring 8x3y−10x2y2+12xy38x^3y - 10x^2y^2 + 12xy^3

Factor 8x3y−10x2y2+12xy38x^3y - 10x^2y^2 + 12xy^3 by extracting the greatest common factor.

Step 1 — Find the GCF: The three terms are 8x3y8x^3y, −10x2y2-10x^2y^2, and 12xy312xy^3. The numerical GCF of 88, −10-10, and 1212 is 22. The shared variables are xx and yy. The lowest power of xx is x1x^1 (or xx), and the lowest power of yy is y1y^1 (or yy). Therefore, the GCF is 2xy2xy.

Step 2 — Rewrite each term using the GCF: Express each term as the product of the GCF and the remaining factors: 2xy⋅4x2−2xy⋅5xy+2xy⋅6y22xy \cdot 4x^2 - 2xy \cdot 5xy + 2xy \cdot 6y^2

Step 3 — Factor out the GCF: 2xy(4x2−5xy+6y2)2xy(4x^2 - 5xy + 6y^2)

Step 4 — Check by multiplying: 2xy(4x2−5xy+6y2)=2xy⋅4x2−2xy⋅5xy+2xy⋅6y2=8x3y−10x2y2+12xy32xy(4x^2 - 5xy + 6y^2) = 2xy \cdot 4x^2 - 2xy \cdot 5xy + 2xy \cdot 6y^2 = 8x^3y - 10x^2y^2 + 12xy^3 ✓

The factored form is 2xy(4x2−5xy+6y2)2xy(4x^2 - 5xy + 6y^2). This demonstrates how to factor polynomials with multiple variables by finding the GCF for each variable independently.
