(y+5)(y-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.

y+5=0

y-7=0

Set the first factor equal to 0.

y+5=0

Subtract 5 from both sides of the equation.

y=-5

y=-5

Set the next factor equal to 0.

y-7=0

Add 7 to both sides of the equation.

y=7

y=7

The final solution is all the values that make (y+5)(y-7)=0 true.

y=-5,7

Solve using the Square Root Property (y+5)(y-7)=0
