MCQ
If we subtract $-3 x^2 y^2$ from $x^2 y^2$, then we get:
- A$-4 x^2 y^2$
- B$-2 x^2 y^2$
- C$2 x^2 y^2$
- ✓$4 x^2 y^2$
✓
Answer
Correct option: D.
$4 x^2 y^2$
D. $4 x^2 y^2$
Solution:
Given, Monomial are $-3 x^2 y^2$ from $x^2 y^2$.
Now we have to substract the first one from the second one.
$x^2 y^2-\left(3 x^2 y^2\right)=x^2 y^2-(-3) x^2 y^2 $
$=x^2 y^2+3 x^2 y^2$
$=(1+3) x^2 y^2 $
$=4 x^2 y^2$
