Factoring 16x2+24xy4x6y16x^2 + 24xy - 4x - 6y

Factor 16x2+24xy4x6y16x^2 + 24xy - 4x - 6y completely.

Step 1 — Check for a GCF: The four terms share a numerical factor of 22. Factor it out: 2(8x2+12xy2x3y)2(8x^2 + 12xy - 2x - 3y)

Step 2 — Factor by grouping: The expression inside the parentheses has four terms, so group them into two pairs. 2[4x(2x+3y)1(2x+3y)]2[4x(2x + 3y) - 1(2x + 3y)] Notice that factoring out 1-1 from the second pair creates the common binomial factor (2x+3y)(2x + 3y). Factor it out: 2(2x+3y)(4x1)2(2x + 3y)(4x - 1)

Step 3 — Check: Verify by multiplying: 2(2x+3y)(4x1)=2(8x22x+12xy3y)=16x2+24xy4x6y2(2x + 3y)(4x - 1) = 2(8x^2 - 2x + 12xy - 3y) = 16x^2 + 24xy - 4x - 6y

The completely factored form is 2(2x+3y)(4x1)2(2x + 3y)(4x - 1).
