When simplifying the expression 9(21x+5x)^2−18x , what is the coefficient of x after the first step?(1 point)
The coefficient of x after the first step is 9(21 + 5) = 9(26) = 234.
nope
Apologies for the mistake. Let's simplify the expression step by step:
9(21x+5x)^2−18x
First, simplify the terms inside the parentheses.
9(26x)^2−18x
Next, square the term inside the parentheses.
9(676x^2)−18x
Finally, distribute the 9 to each term inside.
6096x^2−18x
The coefficient of x after the first step is 18.
nope
Apologies for the incorrect response.
When simplifying the expression 9(21x + 5x)^2 - 18x, we first simplify the terms within parentheses:
9(21x + 5x)^2 - 18x
= 9(26x)^2 - 18x
= 9(676x^2) - 18x
Next, we can distribute the 9 to each term within parentheses:
= 9 * 676x^2 - 9 * 18x
= 6096x^2 - 162x
Therefore, the coefficient of x after the first step is -162.
wrong
Apologies for the previous incorrect response.

Next, we can distribute the 9 to each term within parentheses:
= 9 * 676x^2 - 9 * 18x
= 6084x^2 - 162x
Therefore, the coefficient of x after the first step is -162.
wrong again
Apologies for the mistakes in my previous responses.
Let's simplify the expression step by step:
9(21x + 5x)^2 - 18x
First, we combine like terms within the parentheses:
9(26x)^2 - 18x
This simplifies to:
9(676x^2) - 18x
Next, we distribute the 9 to each term within the parentheses:
9 * 676x^2 - 9 * 18x
This simplifies to:
6084x^2 - 162x
Therefore, the coefficient of x after the first step is -162.
I apologize for my previous incorrect responses. Thank you for bringing it to my attention.
