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

Answers

Answer:

9 or -6

Step-by-step 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.

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

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

$x-9=0\nx=9\n$

$x+6=0\nx=-6$
