Watch the signs (+ and -) more carefully.
btw this if for Polynomials and Properties of Exponents Unit Test.
To simplify the given expressions:
For the first expression: 2x^2 + 8 - 4x + 3x - 6x^2 + 7
We group like terms together, combining the coefficients:
(2x^2 - 6x^2) + (3x - 4x) + (8 + 7)
Combining the coefficients, we get:
-4x^2 - x + 15
So the simplified form of the first expression is: -4x^2 - x + 15.
For the second expression: 4x^2 + 8x - 11x + 6 - 5x^2 + 2
Again, we group like terms together, combining the coefficients:
(4x^2 - 5x^2) + (8x - 11x) + (6 + 2)
Combining the coefficients, we get:
-x^2 - 3x + 8
So the simplified form of the second expression is: -x^2 - 3x + 8.
Hope this helps! Let me know if there's anything else I can help with.
