Did you mean 7 is added to the result after dividing by 6 ? Else how can you add 7 to the divisor if the division has been done? The wording is very odd. According to my interpretation: x/6 + 7 = 4 x/6 = -3 x = -18

type it this way: f(x) = x^5 - 6x^4 + 7x^3 - 10x^2 since complex number zeros always come in conjugate pairs, there is another zero of 1-i so (x -(1+i)) and (1 - (1-i)) are factors expanded gives us: (x-1-i)(x-1+i) = x^2 - x + ix - x + 1 - i - ix + i - i^2 , but i^2 = -1 = x^2...

I found f(3) = 0 , x-3 is a factor then found f(-2) = 0 , so x+2 is a factor divided both of those and got -(2x^2-7x+3) which factored further to -(x-3)(2x-1) so f(x) = -(x-3)^2 (x+2)(2x-1) with zeros at x= -2, 1/2 and 3 , 3 being a double root

If the measurement from the outer edge of the first board to the outer edge of the last board is 144 inches, then there would be 14 spaces between the boards, each measuring 3/8 inch. (14x3/8)+(15x9 1/4)= 144. Now if this section is in the middle of the boardwalk, there would ...
