Question

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

Answer 1

Answer:

x = -1 or x = -3

Step-by-step 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.

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