Answers
4a - 4b - x² - 10x + 5
We have to subtract x² + 10x - 5 from 4a - 4b.
Now, (4a - 4b) - (x² + 10x - 5)
= 4a - 4b - x² - 10x + 5
We have to subtract (- x² + 10x - 5) from 4a - 4b.
Now, (4a - 4b) - (- x² + 10x - 5)
= 4a - 4b + x² - 10x + 5
Notes:
- To perform the subtraction of two expressions, first we write them in proper format and then multiply the respective positive and negative symbols.
- If the expressions contain similar terms like x, x², ..., we have to perform algebraic operations (addition, subtraction) separately among them.
- If they contain no like terms, we just only perform the multiplication of symbols.
- (+) × (+) = (+)
- (+) × (-) = (-)
- (-) × (+) = (-)
- (-) × (-) = (+)

Subtract:- x^2+10x-5 from 4a-4b we get 4a - 4b - x² - 10x + 5
Stepwise explanation is given below:
- We have to subtract x² + 10x - 5 from 4a - 4b.
- In the given equation the valies of x, a, b is not given. So, the perfect answer will not come. The answer will come in the form of an other equation.
- Now, (4a - 4b) - (x² + 10x - 5)
It is simple that the sign out of the bracket is minus. So, the sign inside the bracket would be change.
- Such that the minus sign will change into plus and the plus sign will change into minus.
= 4a - 4b - x² - 10x + 5
