Question

Perform the indicated operation. 7x2/12w - 3x2/12w

Answer 1

`\frac{ {x}^(2) }{3w}`

Explanation:

`\frac{ {7x}^(2) }{12w} - \frac{ {3x}^(2) }{12w} \\ = \frac{ {4x}^(2) }{12w} \\ = \frac{ {x}^(2) }{3w}`

Answer 2

x^2/3w

Explanation:

7x^2/12w - 3x^2/12w

These are like terms, so we can combine them

(7x^2 - 3x^2)/12w

4x^2/12w

We can divide the top and bottom by 4

x^2/3w
