 The parabolas defined by the equations y = x^2 + 4x + 6 and y = 2x^2 + 7x - 4 intersect at points and (a,b) and (c,d), where c >= a. What is c-a?

See the graph here : https://www.desmos.com/calculator/doygww4j6l

 

c =   .844

a  = -11.844

 

c  - a  =   .844  -  ( - 11.844 )  =   .844 + 11.844    ≈  12.688
