4x + 2 = -10x - 20. i have racked my brain about this one.

x = -11/3

Step-by-step explanation:

Start by combining like terms:  6x = -22

Then divide both sides by 6 to isolate x:

x = -11/3

x = -11/3

Step-by-step explanation:

-4x + 2 = -10x - 20

Add 10x to each side

-4x+10x + 2 = -10x+10x - 20

6x+2 = -20

Subtract 2 from each side

6x+2-2 = -20 -2

6x = -22

Divide by 6

6x/6 = -22/6

x = -11/3

false

step-by-step explanation:

4y - 6 + 4y^2 - 9

before simplifying this contains 4 terms

after simplifying

4y -15 + 4y^2

it contains 3 terms

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
