Identify common factors: Identify common factors in both terms.The expression has two terms: \(3x+5)^{2}(2x+7)\ and \(3x−7)(3x+5)\. The common factor in both terms is \(3x+5)\.
Factor out common factor: Factor out the common factor (3x+5). We can write the expression as (3x+5)[(3x+5)(2x+7)+(3x−7)].
Distribute and simplify: Distribute (3x+5) in the first term and simplify the expression inside the brackets.(3x+5)[(3x+5)(2x+7)+(3x−7)] becomes (3x+5)[6x2+21x+10x+35+3x−7].
Combine like terms: Combine like terms inside the brackets.(3x+5)[6x2+21x+10x+35+3x−7] simplifies to (3x+5)(6x2+34x+28).
Factor quadratic expression: Factor the quadratic expression inside the brackets if possible.The quadratic expression 6x2+34x+28 can be factored as 2(3x2+17x+14).
Factor quadratic expression: Factor the quadratic expression 3x2+17x+14. We look for two numbers that multiply to 3×14=42 and add up to 17. These numbers are 2 and 21. So, 3x2+17x+14 can be factored as (3x+2)(x+7).
Write final factored form: Write the final factored form of the original expression.The final factored form is (3x+5)×2×(3x+2)(x+7).
