Log in for more information. Question. Asked 1/19/2016 11 Simplify (5x-2y)(5x+2y) Step 1. Expand using the FOIL Method. Tap for more steps Step 1.1. Apply the distributive property. Step 1.2. Apply the distributive property. The given expression 5x+2(3−2x)+7 can be simplified as shown below. 5x + 2(3−2x) + 7. Open the parenthesis, = 5x + 6 − 4x + 7. Bring the like terms together, = 5x − 4x + 7 + 6. Add the like terms, = x + 13. Hence, The given expression 5x+2(3−2x)+7 when simplified will be equal to x+13.
