Question

Best method to solve quadratic equation x^2 +4x+3=0

Answer 1

x = -1 or x = -3

Explanation:

Let's solve your equation step-by-step.

`x^(2) + 4x + 3 = 0`

For this equation: a=1, b=4, c=3

`1x^(2) + 4x + 3 = 0`

Step 1: Use quadratic formula with a=1, b=4, c=3.

`x =\frac{-b +\sqrt{b^(2) -4ac } }{2a}\\x =\frac{-(4) + \sqrt{(4)^(2)-4(1)(3) } }{2(1)}\\x =(-4 +√(4) )/(2)\\x =-1 /-3`
