x=-0.8

Step-by-step explanation:

x+4x=-4

5x=-4

x=-4/5

x=-0.8

x = -2

Step by Step explanation:

got it right on ed

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1

okay..i will pick 8!
