Distribute common factor: Distribute the common factor (2x+7) in the expression.We notice that (2x+7) is a common factor in both terms of the expression. We can factor it out to simplify the expression.(4x+5)(2x+7)−(3x−2)(2x+7)(2x+7)
Apply distributive property: Apply the distributive property to factor out (2x+7). We can write the expression as (2x+7) multiplied by the difference of the two terms. (2x+7)[(4x+5)−(3x−2)(2x+7)]
Expand second term: Expand the second term inside the brackets.We need to multiply (3x−2) by (2x+7) to simplify the expression inside the brackets.(2x+7)[(4x+5)−((3x−2)(2x+7))]
Perform multiplication: Perform the multiplication (3x−2)(2x+7). We use the FOIL method to expand the product. (3x−2)(2x+7)=3x(2x)+3x(7)−2(2x)−2(7)=6x2+21x−4x−14=6x2+17x−14
Substitute expanded term: Substitute the expanded term back into the expression.Now we replace the expanded term in the expression.(2x+7)[(4x+5)−(6x2+17x−14)]
Distribute negative sign: Distribute the negative sign to the terms inside the brackets.We need to subtract the entire expanded term from (4x+5).(2x+7)[4x+5−6x2−17x+14]
Combine like terms: Combine like terms inside the brackets.We combine the x terms and the constant terms.(2x+7)[−6x2+(4x−17x)+(5+14)](2x+7)[−6x2−13x+19]
Expression factored completely: The expression is now factored completely. We have factored the expression completely, and there are no common factors or further factoring that can be done. (2x+7)(−6x2−13x+19)
