Answer:

x=1±i√5

Step-by-step explanation:

the quadratic equation is in the form :

y=ax²+bx+c

y= 2x²-4x+12

x=(-b±√b²-4ac)/2a

x=-(-4)±√-4²-4(2)(12)/2a

x=4±√16-96/4

x=4±√-80/4

since the number under the square root then √-80=4i√5 ( assuming possitive numbers)

x=(4±4i√5)/4

x=4(1±i√5)/4

x=1±i√5

The equation 3x + 2 = 29 is modeled below.
DanielleElmas [232]

Answer:

Subtract 2 from both sides.

Step-by-step explanation:

Remember to do the opposite of PEMDAS. PEMDAS is the order of operation, and stands for:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

> Also, note the equal sign, what you do to one side, you do to the other side of the equation.

First step is to subtract 2 from both sides of the equation:

3x + 2 (-2) = 29 (-2)

3x = 29 - 2

3x = 27

The second step is to divide 3 from both sides of the equation:

(3x)/3 = (27)/3

x = 27/3

x = 9
