“At first, the equation made me confused... and then your solution to the equation looks easy. Thanks!”

“I see a perfect initial substitution, given the construction of the equation (1:53), as y = x - ½, changing the equation to y^3 - y^2 + y - 52 = 0.”

“This method is a little harder when the found value isn't an integer, but I'm doing it anyway. (2y-1)(2y^2+y+1)=0 leads to y1=1/2.”

“I see a perfect substitution, given the construction of the equation and the need for x to not equal 3 (1:50), y = (x - 3)^(-1).”

“I see letting, with the equation constructed the way it has been (0:24), at least for an initial substitution, y = cubert(37x - 6).”

“An easier finish: a = √(x - 1), b = √(x + 3). We solve the equation to get: a + b = 3. This simplifies the problem greatly.”

“The two integers, given the construction of the equation (2:09), whose respective sum and product are -7 and 6 are -1 and -6.”

“At the 0:43 mark of the video, we have, on the left side of the equation, (3x)^3 - 3[(3x)^2] + 5(3x) - 3, with a good initial substitution being y = 3x.”
“The system to solve is symmetric in x and y, so an obvious first step is to rewrite this system in terms of the elementary symmetric polynomials x + y and xy.”
What could be better
“There is a much better way to solve the equation (x − 3)³ = (4 − x)/4 which does not require rationalizing denominators of expressions for complex solutions.”

“No real values of x and y can make this equation's left side = 0. This indicates a potential issue or a need to consider complex solutions more explicitly.”

“In the seventh line there will be 2*3 in the denominator instead of 2*1. Excuse me for my mistake. (Self-correction, but points out a potential error in the solution).”
“In the fifth line of my comment the crossed part is -12=0 => k^2+k-12=0. (Points out a typo or error in a previous comment/solution).”
“Let x-1=a^2 & x+3=b^2. Therefore a^2+b^2=2x+2=12-(10-2x). This substitution seems overly complex for the given equation.”
