Simplifying algebraic expressions often involves multiplying terms. Let’s look at how to simplify the expression 4y \times 2y
When multiplying algebraic terms, we multiply the coefficients (the numbers in front of the variables) and then multiply the variables. Here’s the step-by-step process:
- Multiply the coefficients: In this case, we have 4 and 2. So, 4 \times 2 = 8
- Multiply the variables: We have y \times y. Remember that y is the same as y^1, so y \times y = y^1 \times y^1 = y^{1+1} = y^2
- Combine the results: Now, we combine the results from steps 1 and 2. So, 4y \times 2y = 8y^2
Therefore, the simplified expression is 8y^2.
This principle extends to more complex expressions with different variables and exponents. If you find yourself struggling with these concepts or need more in-depth explanations, seeking help from a maths tutor can be incredibly beneficial. They can provide targeted support to strengthen your understanding.
