Answer: With a variable. A variable is a letter you use in an equation , like this: 7+x=14, X is a classic one but you can use any letter u please! (In my school at least.)
- Quadratic Formula:
, with a = x^2 coefficient, b = x coefficient, and c = constant
With our equation, plug in the values:

Next, solve the exponent and multiplications:

Next, solve the subtraction:

Next, factor out i (i = √-1):

Next, solve the square root:

Lastly, divide and <u>your answer is:</u>
