x^4 + 10x + 18 - x^4 - 3x + 2
Is this 13x + 16?
10 - 3 = 7
18 + 2 = 20
so
7 x + 20
Hmmm.
x^4 + 10x + 18 - (x^4 - 3x + 2) does equal 13x+16
see what a difference some parentheses can make?
Oops...forgot the parentheses. Thanks Damon and Steve!
To determine if the given expression simplifies to 13x + 16, we need to combine like terms.
The expression can be rewritten as:
(x^4 - x^4) + (10x - 3x) + (18 + 2)
Simplifying each pair of like terms, we have:
0x^4 + 7x + 20
Since there is no x^4 term, we can simplify further:
7x + 20
Comparing this simplified expression to 13x + 16, we can see that they are not equal. Therefore, the original expression does not simplify to 13x + 16.
