Answer 2

Answer:

nark me as brainliest and follow me

Step-by-step explanation:

Explanation:

For the quadratic equation

ax2+bx+c=0

the formula for the roots is

x=−b±√b2−4ac2a

(1)

Identify the values for

a,b,&c

x2+4x+3=0

cmp

ax2+bx+c=0

a=1

b=4

c=3

(2)

Substitute these numbers into eh formula

x=−4±√42−(4×1×3)2×1

(3)

Carefully proceed and do the calculations

x=−4±√42

x=−4±22

now calculate the two separate solutions

x1=−4+22=−22=−1

x2=−4−22=−62=−3
