How do you solve (2x-7)(5x+3)=0
sammy [17]

Step-by-step explanation:

First I do it as separate equations 2x-7=0 and 5x+3=0. In this equation you get two answers so you first answer 2x-7=0

2x-7=0

    +7   +7

2x=7

/2   /2

x=7/2

Then do 5x+3=0

                     -3  -3

                5x=-3

                    /5 /5

                x=  -3/5

Then you can check by putting them back in.
