Question

Solve x(x-1)=20 plzz solve and give me the ans

Answer 1

Answer:

x² - x = 20

x² - x -20 = 0

Solving this quadratic equation we get:

x² - 20x + x - 20 = 0

x(x-20) +1 (x-20) = 0

(x-20)(x+1) = 0

So value of x is: x-20 = 0                      or                      x+1 = 0

                            x = 20                                                   x = -1

Value of x = 20 or -1
