Recognize as difference of squares: Recognize the expression as a difference of squares.The given expression is in the form of a2−b2, which is a difference of squares.The difference of squares can be factored using the identity a2−b2=(a+b)(a−b).Here, a=(5x+1) and b=(3x+7).
Apply identity: Apply the difference of squares identity.Using the identity from Step 1, we can write the expression as:(5x+1+3x+7)(5x+1−3x−7)
Simplify each factor: Simplify each factor.Now we simplify the expressions inside the parentheses.First factor: (5x+1+3x+7)=(5x+3x)+(1+7)=8x+8Second factor: (5x+1−3x−7)=(5x−3x)+(1−7)=2x−6
Factor out common terms: Factor out common terms if possible.Looking at the factors8x+8 and 2x−6, we can factor out common terms.First factor: 8x+8 can be factored as 8(x+1)Second factor: 2x−6 can be factored as 2(x−3)
Write final factored form: Write the final factored form.The completely factored form of the expression is:8(x+1)×2(x−3)
Combine the constants: Combine the constants.Multiplying the constants 8 and 2, we get 16.The final factored form is:16(x+1)(x−3)
