We need to solve for the first derivative of the function `dy/dx = d/dx[18x^2+8x18]` `dy/dx = 18*d/dx(x^2)+8*d/dx(x) d/dx(18)` `dy/dx = 18*2(x^(21))+8(1) 0` `dy/dx = 36x+8`

Find every combination of `+p/q` These are the possible roots of the polynomial function. `+1, + 1/2,+ 1/4,+3,+3/2,+3/4` Since `1/2` is a known root, divide the polynomial by `(x  1/2)`...

We need to solve `2cos^2x1=1` Add 1 on both sides of the equation. `2cos^2x=2` Divide each term in the equation by 2. `cos^2x=1` Take the square root of both sides of the equation to eliminate the...

Remove the parentheses that are not needed from the expression. `x^2 + 5x^2 + 6 + 1/(x^2 + 3)` Since `x^2` and `5x^2` are like terms, add `5x^2` to `x^2` to get `6x^2` `6x^2 + 6 + 1/(x^2 + 3)`...

We need to determine the value of `x ` in `x6sqrt(x)=8` First, we isolate the term containing square root. So we have `6sqrt(x) =x+8` Then if we square both sides, we get `36x=(x+8)^2` By using...
