Use the quadratic formula to find the solutions. In this case, the values are a=1, b=-3, and c=7. x>(-b+-sqrt(b^(2)-4ac))/(2a) where ax^(2)+bx+c=0 Simplify the section inside the radical. x>(3+-isqrt(19))/(2(1)) Simplify the denominator of the quadratic formula. x>(3+-isqrt(19))/(2) ------------------------------------------------ Simplify the expression to solve for the + . x>(3+isqrt(19))/(2) Simplify the expression to solve for the -. x>(3-isqrt(19))/(2) Since the solution to the quadratic is imaginary, there are no solutions to the inequality. No Solution

the graph of the equation is above the X-axis so for all the real number the solution exist
