Given the statement:
Subtract -2x-10 from 10x^2+3
Solution:
This can be written in numerical expression as,
10x^2 + 3 - (-2x -10)
It is a common rule that whenever a negative sign is introduced to a negative sign, the banswer will be positive. Hence similar signs result to a positive answer, while opposite signs result to a negative answer. Therefore -2x -10 will become 2x + 10
10x^2 + 3 + 2x + 10
Combine like terms.
10x^2 + 2x + 13
Final answer:
10x^2 + 2x + 13
