We keep the 2x^2 because we can only subtract something from that if it also is squared. From there, we subtract the 7x from 2x^2-11. Since there is no previous x's in the 2x^2-11, we just make it -7x. So, without even continuing the problem, we see that A) is the correct answer because it is the only one with -7x.
After subtracting (7x - 9) from 2x² - 11 we get 2x² - 7x - 2 the answer is 2x² - 7x - 2 option (A) is correct.
What is an expression?
It is defined as the combination of constants and variables with mathematical operators.
We have two expressions:
7x - 9 and
2x² - 11
Subtracting:
= (2x² - 11) - (7x - 9)
= 2x² - 11 - 7x + 9
= 2x² - 7x - 2
Thus, after subtracting (7x - 9) from 2x² - 11 we get 2x² - 7x - 2 the answer is 2x² - 7x - 2 option (A) is correct.
