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.
