Create an Algebraic Expression: Using Parameters a=1, b=2, c=0

Q: What does it mean to 'create an algebraic expression' with parameters?

It means to build a mathematical expression using the standard quadratic form $ ax^2 + bx + c $ where a, b, and c are the given parameter values. You substitute the numbers into their proper positions.

Q: Why do we omit the c term when c=0?

When c=0, adding zero doesn't change the value, so $ x^2 + 2x + 0 = x^2 + 2x $. It's mathematically correct to include +0, but we typically simplify by removing it.

Q: What if I got a different answer choice?

Double-check your substitution! Make sure you're using the correct positions: a goes with $ x^2 $, b goes with $ x $, and c is the constant term. With a=1, b=2, c=0, the only correct expression is $ x^2 + 2x $.

Q: Can the expression be written in a different order?

Yes! $ x^2 + 2x $ and $ 2x + x^2 $ are equivalent. However, standard form puts the highest power first, so $ x^2 + 2x $ is preferred.

Understand the problem

Create an algebraic expression based on the following parameters:

$a=1,b=2,c=0$

Step-by-step solution

To solve this problem, we'll follow these steps:

Step 1: Identify the given information
Step 2: Apply the standard quadratic formula
Step 3: Perform the substitution

Now, let's work through each step:
Step 1: We are given $a = 1$ , $b = 2$ , and $c = 0$ .
Step 2: We'll use the formula $y = ax^2 + bx + c$ to form our expression.
Step 3: By substituting the given values, we get:

Replace $a$ with 1: $1x^2 = x^2$ .
Replace $b$ with 2: $2x = 2x$ .
Replace $c$ with 0: since $c = 0$ , it does not contribute to the expression, so we can omit this term.

Therefore, we combine the terms to form the expression: $x^2 + 2x$ .

The correct answer choice based on our derived expression is: $x^2 + 2x$ .

Final Answer

$x^2+2x$

Key Points to Remember

Essential concepts to master this topic

Standard Form: Use $ax^2 + bx + c$ as the template
Substitution: Replace a=1, b=2, c=0 to get $1x^2 + 2x + 0$
Simplification: Remove zero terms and coefficient 1: $x^2 + 2x$ ✓

Common Mistakes

Avoid these frequent errors

Adding parameters as constants instead of coefficients
Don't write a+b+c = 1+2+0 = 3 as your expression! This treats parameters as numbers to add, not as coefficients for variables. Always use the standard quadratic form $ax^2 + bx + c$ where a, b, c are coefficients.

FAQ

Everything you need to know about this question

What does it mean to 'create an algebraic expression' with parameters?

It means to build a mathematical expression using the standard quadratic form $ax^2 + bx + c$ where a, b, and c are the given parameter values. You substitute the numbers into their proper positions.

Why do we omit the c term when c=0?

When c=0, adding zero doesn't change the value, so $x^2 + 2x + 0 = x^2 + 2x$ . It's mathematically correct to include +0, but we typically simplify by removing it.

Do I need to write 1x² or just x²?

Both are correct! Since multiplying by 1 doesn't change the value, $1x^2 = x^2$ . We usually omit the coefficient 1 for cleaner notation.

What if I got a different answer choice?

Double-check your substitution! Make sure you're using the correct positions: a goes with $x^2$ , b goes with $x$ , and c is the constant term. With a=1, b=2, c=0, the only correct expression is $x^2 + 2x$ .

Can the expression be written in a different order?

Yes! $x^2 + 2x$ and $2x + x^2$ are equivalent. However, standard form puts the highest power first, so $x^2 + 2x$ is preferred.
