x² + 3x + 7 = 0 [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

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

plug in the numbers into the variables

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

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

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

your answer is a

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