Question

Which of the following is a soultion to the quadratic equation below x^2 - 3x - 54 =0

Answer 1

9 or -6

Explanation:

To solve, I would suggest factoring.

You need to find two numbers which can be multiplied for 54 and also combined in some way to get 3. In this case, 9 and 6 are perfect.

`x^2-3x-54=0\\(x-9)(x+6)=0`

Next, you can set both of your terms equal to zero to find your possible solutions.

`x-9=0\\x=9\\`

or

`x+6=0\\x=-6`
