Algebraically find the x-coordinates where the line y=2x+3 intersects the circle (x-3)^2 + (y+6)^2= 50 ** please help due soon **

Which expression is equivalent to the expression below? (6c^2 + 3c) / (-4c + 2) / (2c + 1) / (4c - 1)a. 3c(2c-1) / (2c + 1)b. -3c(2c-1)^2 / (2c + 1)^2c. 3cd. -3c(just took the test its d. -3c)
