This is a product of two expressions that is equal to zero. Note that any x value that makes either (2x+3) or (3x−7) zero, will make their product zero.
So now by putting (2x+3) and (3x−7) equal to zero, we get
2x+3=0
2x+3−3=0−3
2x=−3
x=−32
similarly,
3x−7=0
x=73
So now substituting either x=-3/2 or x=7/3 into the equation will result in the true statement 0=0, so they are both solutions to the equation.
