Question

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

Answer 1

Answer:

x^2/3w

Step-by-step 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

Answer 2

Answer:

$\frac{ {x}^{2} }{3w}$

Step-by-step explanation:

$\frac{ {7x}^{2} }{12w} - \frac{ {3x}^{2} }{12w} \\ = \frac{ {4x}^{2} }{12w} \\ = \frac{ {x}^{2} }{3w}$
