Identify the coefficients based on the following equation
To solve this problem, we'll start by rearranging the given equation:
Now, let's work through each step:
Step 1: The general form we aim for is .
Step 2: Rearrange the given equation:
Start by rearranging the terms to resemble . We write the equation as:
Step 3: Now, comparing this with the standard form , we identify the coefficients:
Therefore, the correct parameters for the equation are , , and .
Checking against the answer choices, choice 3: matches our result.
What is the value of the coefficient \( c \) in the equation below?
\( 4x^2+9x-2 \)
Because the equation isn't in standard form yet! You need to correctly identify coefficients. The constant term changes sign when you move it across the equals sign.
Use the pattern a-b-c: a goes with x², b goes with x¹, and c is the constant (no x). Think alphabetical order matching decreasing powers!
Then b = 0! Every quadratic has the form ax² + bx + c, but sometimes b or c can be zero. Don't skip them - write b = 0 explicitly.
Because you moved it across the equals sign! When you rearrange to standard form, the 6 becomes -6. Always pay attention to sign changes.
The terms can be in any order, but standard form convention is highest power first: ax² + bx + c. This makes coefficient identification easier and more consistent.
