What is the equivalent expression for the expression of the squart root x+3

Solve each equation using the quadratic formula. find the exact solutions. 6n^2 + 4n - 11

How is the equation of this circle written in standard form? x2 + y2 - 6x + 14y = 142 a) (x - 3)2 + (y + 7)2 = 200 b) (x+ 3)2 + (y - 7)2 = 200 (x - 6)2 + (y + 14)2 = 142 d) (x+6)2 + (y- 14)2 = 142

Need solving this 2nd limit problem.
