Factor completely 2x^2+4x-2

2x^2+4x-2  =  2 * (x - 1 -) * (x - 1 + )

Step-by-step explanation:

Factor completely 2x^2+4x-2

2x^2+4x-2 =  2* (x^2 + 2x - 1)

x = 1  +  root( 4 - 4*(-1))/2

x = 1 + root(2)

and x = 1 - root(2)

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.  

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
