In the process of solving 2x3 + 7x2 + 9x + 10 = 0 you test 1, 2, 5, and 10 as possible zeros and determine that none of them are actual zeros. You then discover that - 5/2 is a zero. You calculate the depressed (resulting) polynomial to be 2x3 + 2x + 4. Do you need to test 1, 2, 5, and 10 again? Why or why not?

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
