Answer:
(x−7)(x+5)=0
If any individual factor on the left side of the equation is equal to 0, the entire expression will be equal to 0.
x−7=0x+5=0
Set the first factor equal to 0 and solve.
x=7
Set the next factor equal to 0 and solve.
x=−5
The final solution is all the values that make (x−7(x+5)=0 true. x={7,−5}
