Recognize as difference of squares: Recognize the expression as a difference of two squares. The given expression is a difference of two squares because it can be written as A4−B4, where A=(3x−4y) and B=x.
Apply formula: Apply the difference of squares formula.The difference of squares formula is A2−B2=(A−B)(A+B). In this case, we can apply the formula to A2 and B2, where A2=(3x−4y)2 and B2=x2.
Write as difference of squares: Write the expression as a difference of squares.Using the formula from Step 2, we can write the expression as:((3x−4y)2)2−(x2)2=((3x−4y)2−x2)((3x−4y)2+x2)
Expand terms: Expand the terms inside the parentheses.We need to expand (3x−4y)2 and x2:(3x−4y)2=9x2−24xy+16y2 (by squaring each term and applying the distributive property)x2=x2 (no expansion needed)
Substitute expanded terms: Substitute the expanded terms back into the factored form.Substitute the expanded form of (3x−4y)2 into the factored expression from Step 3:(9x2−24xy+16y2−x2)(9x2−24xy+16y2+x2)
Combine like terms: Combine like terms in each factor.In the first factor, combine 9x2 and −x2 to get 8x2. In the second factor, combine 9x2 and x2 to get 10x2:(8x2−24xy+16y2)(10x2−24xy+16y2)
Check for further factorization: Check for any further factorization. The terms within each factor do not have a common factor, and the expression cannot be factored further.
