Answer 1

Answer:

Step-by-step explanation:

Step 1: Add -2x to both sides.

|x2+4x+3|+2x+5+−2x=0+−2x

|x2+4x+3|+5=−2x

Step 2: Add -5 to both sides.

|x2+4x+3|+5+−5=−2x+−5

|x2+4x+3|=−2x−5

Step 3: Solve Absolute Value.

|x2+4x+3|=−2x−5

We know eitherx2+4x+3=−2x−5orx2+4x+3=−(−2x−5)

x2+4x+3=−2x−5(Possibility 1)

x2+4x+3−(−2x−5)=−2x−5−(−2x−5)(Subtract -2x-5 from both sides)

x2+6x+8=0

(x+2)(x+4)=0(Factor left side of equation)

x+2=0 or x+4=0(Set factors equal to 0)

x=−2 or x=−4

x2+4x+3=−(−2x−5)(Possibility 2)

x2+4x+3=2x+5(Simplify both sides of the equation)

x2+4x+3−(2x+5)=2x+5−(2x+5)(Subtract 2x+5 from both sides)

x2+2x−2=0

For this equation: a=1, b=2, c=-2

1x2+2x+−2=0

x=

−b±√b2−4ac

2a

(Use quadratic formula with a=1, b=2, c=-2)

x=

−(2)±√(2)2−4(1)(−2)

2(1)

x=

−2±√12

2

x=−1+√3 or x=−1−√3
