Question

how much larger is 8x²-9y² than 3x²-2y². A proper answer will be selected as brainliest.....
with explanation pls​

Answer 1

Answer:

$5x^2-7y^2$

Step-by-step explanation:

Your question is a bit vague, but based on the fact that this is labeled as "primary school", then I would assume the question is asking about the difference of the two expressions.

Remember that $x$ and $y$ are just "names" for numbers. If you were instead asked to "how much larger is 13 than 9?" then you would just substract the terms:

$13-9 = 4$.

Then 13 is larger than 9 by 4.

Similarily, you can, in some sense, do the same with $8x^2-9y^2$ and $3x^2-2y^2$:

$(8x^2-9y^2) - (3x^2-2y^2) = 8x^2 - 9y^2 -3x^2 +2y^2 = 5x^2 - 7y^2$

Hence, one could say that $8x^2-9y^2$ is bigger than $3x^2-2y^2$ by $5x^2-7y^2$.

Note that I might very well have misinterpreted your question.
