Question

add 3x square y, -5x square y,-x square

Answer 1

Answer:

The solution to this question, i.e, 3$x^{2}$y + (-5$x^{2}$y) + (-$x^{2}$) is -2$x^{2}$y - $x^{2}$, can also be written as -(2y+1)$x^{2}$

Step-by-step explanation:

The question is, add 3x square y, -5x square y,-x square

Lets rewrite the question as following,

Add 3$x^{2}$y, -5$x^{2}$y,-$x^{2}$,

i.e., 3$x^{2}$y + (-5$x^{2}$y) + (-$x^{2}$)

removing the brackets, (+ multiplied by - becomes -)

therefore,  3$x^{2}$y - 5$x^{2}$y - $x^{2}$

Now, only the coefficients of same expression can be added or subtracted, hence,

3$x^{2}$y - 5$x^{2}$y - $x^{2}$

= (3 - 5)$x^{2}$y - $x^{2}$

= -2$x^{2}$y - $x^{2}$

this is the final solution

it can also be written as,

-(2y+1)$x^{2}$
