One factor of one factor of f(x)=5x^3+5x^2-170x + 280 is (x +
7). what are all the roots of the function? use the remainder theorem.
x = –4, x = –2, or x = 7
x = –7, x = 2, or x = 4
x = –7, x = 5, or x = 280
x = –280, x = –5, or x = 7

Option 2 is correct

Step-by-step explanation:

We have been given an expression

Since, we have given a factor (x+7) that means at x=-7 the value of given expression will be zero

Similarly we have to check the given points where  they are giving values 0.

Let us check at x=-4 that means put x=-4 in given expression we will get

We are getting

Hence, x=-4 is dicarded

Hence, option 1 is discarded.

Now, we will check at x=2 we will get

Hence, x=2 is factor of given function.

Now, we will check at x=4

Hence, x=4 is also a factor of given function.

Option 2 is correct

p = 6s

step-by-step explanation:

a mantle plume is an upwelling of abnormally hot rock within the earth's mantle. as the heads of mantle plumes can partly melt when they reach shallow depths, they are thought to be the cause of volcanic centers known as hotspots and probably also to have caused flood basalts.
