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}
It is the equation in the simplest form
4x+2=3x
-2
4x=3x-2
-3
4x-3x=2
1x=2
1x/1x= 2/1
X=2
3.2 -9x+ 7.1 -3x
= (-9x -3x)+ (3.2+ 7.1) (combine like terms)
= -12x+ 10.3
The final answer is -12x+ 10.3~
