Solve for the variable:
1. (x-3)² = - 10x +25
2. (x+4)³ = x³ + 12x² - 16x

The answer to your question is:

1) x = 4

2) x = -2

Step-by-step explanation:

a)                     (x-3)² = x^{2} - 10x +25

                     x² - 6x + 9 = x² - 10x + 25

                    10x - 6x = 25 - 9

                     4x = 16

                     x = 4

b)

                                   (x+4)³ = x³ + 12x² - 16x

               x³ + 3(x²)4 + 3x(16) + 4³= x³ + 12x² - 16x

              x³ + 12x² + 48x + 64 = x³ + 12x² - 16x

               48x + 64 = 16x

               48x - 16x = -64

                32 x = -64

                x = -64/2

               x = -2
