Online "^" is used to indicate exponents.
(2x^8 – x^3 + 4x^2 + 5) – (8x^7 + 8x^3 – 4x)
2x^8 – x^3 + 4x^2 + 5 – 8x^7 - 8x^3 + 4x
Combine like terms.
A NUMBA
To subtract the given expression, we will distribute the negative sign to each term inside the second parentheses. So, the expression becomes:
(2x^8 – x^3 + 4x^2 + 5) + (-8x^7 - 8x^3 + 4x)
Now, let's combine like terms:
2x^8 + (-8x^7) - x^3 + (-8x^3) + 4x^2 + 4x + 5
To combine the terms with the same exponent, simply add or subtract the coefficients (numbers in front of the variables) while keeping the variable and exponent the same:
(2x^8 - 8x^7) - (x^3 + 8x^3) + 4x^2 + 4x + 5
Now, grouping the like terms together:
2x^8 - 8x^7 - 9x^3 + 4x^2 + 4x + 5
So, the final answer after subtracting the given expression is: 2x^8 - 8x^7 - 9x^3 + 4x^2 + 4x + 5.
