How do I solve this? Step by step
Answer:
24.
Step-by-step explanation:
Substitute each instance of x with a 3.
That leaves us with 3^2 + 3x - 5 + 3^2 - 3x + 11.
Combine like terms.
2(3^2) + 6.
Simplify.
2(9) + 6
18 + 6
24.
Answer:
24
Step-by-step explanation:
To solve this equation, you can first simplify the equation by combining like terms. For example, we have two positive x²'s meaning we can simplify this to 2x². After simplifying you should get:
2x² + 6
(We no longer have any values with just x since the positive 3 and negative 3 cancel each other out)
Now, you need to input 3 wherever there is an x. I would suggest putting parenthesis wherever you input this value to avoid confusion.
You should get this:
2(3)² + 6 =
From there, you can start solving the equation to get your answer. You should get something similar to this:
2(9) + 6 =
18 + 6 = 24
