Simplify x² + 3½x²: Combining Like Terms with Mixed Numbers

Question

$(+x^2)+(+3\frac{1}{2}x^2)=$

00:00 Simply

00:03 Find the point (X squared) on the axis

00:08 Add the expression on the right (positive) side of the axis

00:17 Every number's coefficient is 1

00:23 Collect like terms

00:27 And this is the solution to the question

To solve this problem, we will add the coefficients of the like terms:

Step 1: Identify the given expressions: $(+x^2)$ and $(+3\frac{1}{2}x^2)$ .
Step 2: Add the coefficients of the terms. The coefficients are $1$ for $x^2$ and $3.5$ for $3\frac{1}{2}x^2$ .
Step 3: Add these coefficients: $1 + 3.5 = 4.5$ .
Step 4: Multiply the sum of the coefficients by $x^2$ .

By following these steps, we obtain the expression $4.5x^2$ . Thus, the solution is $4\frac{1}{2}x^2$ .

$4\frac{1}{2}x^2$
