Answer:
125x^15
Step-by-step explanation:
Hope this helps! :)
You can only add x terms together only if they have the same exponent. For example you can add 2x^2 and x^2 but you cannot add x^2 and x^3.
In this particular problem, you can add 4x^4 and x^4, and x and 8x. So,
<span>
(x + 4x^4) + (x^4 - 2 + 8x)
</span>= 5x^4 + 9x -2
1) A. since, if you put the numbers into the equation (one at a time) the equation = 0 each time, which is true.
2) I think I've been taught to complete the square slightly differently
x^2 - 18x - 17 = 0
(x-9)^2 - 81 -17 = 0
(x-9)^2 - 98 = 0
I hope you can get something from that
