Solve the equation, showing each step of the solution.
-3x + 25 = 40

x= -5

Step-by-step explanation:

-3x + 25 = 40

you want to put x terms on one side, numbers on another side

subtract 25 on both sides

-3x = 15

divide both sides by -3

x= -5

please hit the heart button :)

well for me I think

Step-by-step explanation:

-3x=40-25

-3x=15

x=15/-3

x=-5

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1
