this is all i got sorry if it wrong

( x − 4 ) ( x + 7 ) = 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 − 4 = 0 x + 7 = 0

Set the first factor equal to 0 and solve. x=4 Set the next factor equal to 0 and solve. x = − 7 The final solution is all the values that make ( x − 4 ) ( x + 7 ) = 0 true. x = 4 , − 7
