What is the best approximation of the positive solution to the quadratic function 12x^2-4x-10?

if you was gonna solve for a, a is a   < -12

x=-7

step-by-step explanation:

x+3=-10

-10+3=-7

x=-7

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.
