The equation x ^ 2 + 5x + n = 0 about X can be transformed into (x + P) ^ 2 = 9 by using the collocation method, so the equation x ^ 2-5x + n = 1 about X can also be transformed into (x + P) ^ 2 = 9 by using the collocation method

The equation x ^ 2 + 5x + n = 0 about X can be transformed into (x + P) ^ 2 = 9 by using the collocation method, so the equation x ^ 2-5x + n = 1 about X can also be transformed into (x + P) ^ 2 = 9 by using the collocation method

From the meaning of the title: (x + P) &# 178; - 9 = x & # 178; + 5x + n
∴x²-5x+n=x²-2px+p²-9=(x-p)²-9
That is, (X-P) &# 178; - 5x + n = 1, that is, (X-P) &# 178; - 9 = 1, that is, (X-P) &# 178; = 10
