Identify Factors: Identify common factors in both terms of the expression.The expression is (x+5)(3x+7)+(2x+7)(3x+7)2. We can see that (3x+7) is a common factor in both terms.
Factor Out Common Factor: Factor out the common factor (3x+7). We can write the expression as (3x+7) times another factor. To find this other factor, we divide each term by (3x+7). (3x+7)[(x+5)+(2x+7)(3x+7)]
Simplify Inside Brackets: Simplify the expression inside the brackets.Now we need to simplify the expression inside the brackets by distributing (3x+7) in the second term.(3x+7)[(x+5)+(2x+7)(3x+7)]= (3x+7)(x+5+(2x+7)(3x+7))
Expand Product: Expand the product (2x+7)(3x+7). To simplify further, we need to multiply (2x+7) by (3x+7). (2x+7)(3x+7)=6x2+21x+14x+49=6x2+35x+49
Combine Like Terms: Combine like terms and rewrite the expression.Now we combine the like terms from the expansion and rewrite the expression.(3x+7)(x+5+6x2+35x+49)= (3x+7)(6x2+36x+54)
Factor Quadratic Expression: Factor the quadratic expression if possible.We need to check if the quadratic expression 6x2+36x+54 can be factored further. However, this is a mistake because the correct expression inside the brackets should be x+5+6x2+35x+49, not 6x2+36x+54.
