Problem 54
Question
Fill in each blank. $$ 36 x^{2}=2 x \cdot $$ ____
Step-by-Step Solution
Verified Answer
The missing term is \(18x\).
1Step 1: Identify the Key Equation Components
Let's list the components of the given equation: left side contains \(36x^2\), and the right side contains \(2x\) multiplied by something we need to determine.
2Step 2: Simplify Left Side for Comparison
Observe that \(36x^2\) can be rewritten as \((2x)(18x)\). This helps us to find the missing term by matching it with the equation on the right side.
3Step 3: Match and Determine Missing Term
Now, compare this with the right side of the initial equation: \(2x \cdot ? = 36x^2\). The term that completes the equation must be \(18x\).

Solving Equations
Solving equations is like solving puzzles. You have to find the missing pieces to make everything fit perfectly. In algebra, equations are like balance scales, each side must be equal. Solving them means finding out what value makes the equation true. Here, we're dealing with a polynomial equation, which involves variables raised to a power. To solve it, you need to determine what multiplies with the given term to yield the expression on the other side. In this exercise, we aim to find the missing term in the equation: \(36x^2 = 2x \cdot ?\). To find the unknown, we rewrite the equation so both sides match perfectly. By understanding the structure of these equations, we effectively unravel the problem, finding the piece that fits.
Algebraic Expressions
Algebraic expressions are like sentences in math, where numbers and variables come together to describe an idea. They include terms, which can be numbers, variables, or a combination of both. In this exercise, \(36x^2\) is an algebraic expression on the left side of the equation. On the right side, we have \(2x\) multiplied by an unknown term. The goal is to decode the expression by figuring out what this unknown term is. Algebraic expressions can have different combinations of factors and coefficients, and recognizing patterns in these expressions helps us simplify and solve them. When you dissect these expressions and understand what holds them together, finding the unknown becomes much simpler.
Simplification in Algebra
Simplification in algebra is about making equations easier to understand. You can think of it like cleaning a messy room. You organize the terms so they're easy to handle. Simplification involves combining like terms and using operations to make an equation easier to work with. In our exercise, we looked at \(36x^2\) and broke it down into simpler parts, \((2x)(18x)\). This process of simplification helps identify the missing piece that completes the equation. By doing so, we make it easier to see that the missing term must be \(18x\) because when multiplied with \(2x\), it results in \(36x^2\). Simplifying equations makes them more manageable and reveals the hidden components that solve the puzzle.
