Question

-) (3x - 7y + 1)2 – (2x - 9y - 8)2​

Answer 1

Answer:

Step-by-step explanation:

First we have to multiply values outside the bracket from inside

So - and 2 will be multiplied by values inside brackets

So the value will become

(-3x+7y-1)2 (-2x +9y+8)2

Then

-6x + 14y - 2 - 4x + 18y + 8

Then we will add and substract values according to their constant

-6x - 4x + 14y + 18y - 2 + 8

Then the answer will be

-10x + 32y + 62
