Open the line segment rotation application line type of AB is a 90° rotation counterclockwise of line segment CD click the 90° counter clockwise button on line segments A B and C the same what does this mean about how a line segment changes when you rotate it.

x is variable or an unknown value to find

example:

2x = 5 which means x = 3

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
