Correctly cutting the square - in the textbook there is a formula and examples, then transfer all the numerical designations to the right side, and all with the X to the left, not forgetting to change the sign to the opposite. In the end, you just need to divide the net number into one of the factors, and you will know X. Reveal the square of the amount. I do not remember exactly, but it seems that subtraction can be represented as a sum, where the second term is with a minus, that is, not (x - 2), but (x + (-2)) and disclose as a square of the amount according to the rules.
