Question

What are the exact solutions of x2 + 7x + 3 = 0?

Answer 1

x^2 + 7x +3
use the quadratic equation to solve

b+- sqrt: {b^2 - 4ac} all over 2a

Answer 2

Quadratic formula: X = (-b ±√(b²-4ac))/(2a) = ( -7±√( 49 -12))/( 2)
positive discriminant = 37; two real roots: X=-6.541381265149109 and -0.45861873485089033

Answer 3

X = -3.5 ±√( 9.25)
