Hey there!
The above question is adding or subtracting the polynomials.
We are given two polynomials and those are needed for be subtracted as the above symbol " — " says.
We are also to remember that, A negative number multiplied by positive number gives negative number.
And,
A negative number multiplied by a negative number gives positive number.
– × – = +
+ × – = –
Now,
(9x² - 3x - 6) - (4x + 5 – 2x²)
= (9x² - 3x - 6) - (4x + 5 – 2x²)
= (9x² - 3x - 6) - 4x - 5 + 2x²
= x²( 9 + 2 ) -x ( 3 + 4 ) -1 ( 6 + 5 )
= 11x² - 7x - 11 .
Hope helped!
