Solve with quadratic formula

3x+6x+3=0

6x^2-2x+1=0

2x^2+4=0

-3x=2x^2-4

-5x^2-6=-4x

Step-by-step explanation:

3x+6x+3=0

9x+3=0

9x=0-3

9x=-3

x=-3/9

simplify

x=-1/3

x=-1/3

6x^2-2x+1=0

Apply the quadratic formula with a=6, b=-2 and c=1.

(1+sqrt(5)*i)/6, (1-sqrt(5)*i)/6

2x^2+4=0

2x^2=0-4

2x^2=-4

x^2=-4/2

x^2=-2

x=i*sqrt(2), -i*sqrt(2)

i*sqrt(2), -i*sqrt(2)

-3x=2x^2-4

2x^2-(-3x)-4=0

2x^2+3x-4=0

Apply the quadratic formula with a=2, b=3 and c=-4.

(-3+sqrt(41))/4, (-3-sqrt(41))/4.

-5x^2-6=-4x

-5x^2-(-4x)-6=0

-5x^2+4x-6=0

5x^2-4x+6=0

Apply the quadratic formula with a=5, b=-4 and c=6.

(2+sqrt(26)*i)/5, (2-sqrt(26)*i)/5.

answer: 2x + 2 − 2 = 10 − 2; subtraction property of equality
