Answer from: Quest

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

x = \frac{-b+/-\sqrt{b^2-4ac} }{2a}     (+/- is this ±)

plug in the numbers into the variables

x = \frac{-3+/-\sqrt{3^2-4(1)(7)} }{2(1)}

x=\frac{-3+/-\sqrt{9-28} }{2}

x=\frac{-3+/-\sqrt{-19} }{2}

your answer is a

What is the solution to this equation? x^2+3x+7=0
