Use the grouping method to factor the polynomial in the box completely.
use the caret symbol ( ^ ) to write exponents; for example, enter x2 as x^2. write each factor as a polynomial in descending order.

5x7 + 40x5 + 30x4

5x^4(x^3+8x+6) this is the correct answer

The answer is that the rate of change is $50 per 1 monthhope this ; )
