'Solve equation by the quadratic formula: List the solutions, separated by commas_ 2r2 + 3r + 14 = 7'
Added by Barbara V.
Step 1
r = (-3 ± √(3^2 - 4(2)(7))) / 2(2) r = (-3 ± √(-47)) / 4 Since the square root of a negative number is not a real number, this equation has no real solutions. The solutions are complex numbers. Show more…
