Solve 3x^2 + 2x + 7 = 0. Round solutions to the nearest hundredth.

x ≈ - 1.90 and x ≈ 1.23

x ≈ - 1.23 and x ≈ 1.90

x ≈ - 0.44 and x ≈ - 3.56

No real solutions

The quadratic formula is - b + / - the square root of b squared - 4 (ac) all over 2a.

-2 + / - the square root of 4 - 4 (3*7) all over 2*3.

-2 + / - the square root of - 80

Since the square root of 80 is irrational, the equation has no solution

3x^2 + 2x + 7 = 0

using the quadratis formula

x = [ - 2 + / - sqrt (2^2 - 4*3*7) ] / 6

Hint the numbers in parentheses after the square root work out to negative 80)
