a root number is a number in which satifies the unknown value of an equation. For example: x² - 1 = 0 the root of this equation would be 1 or -1 since when multiplied by itself, they both equal 1. Therefore, 1 - 1 = 0
x^2-3x-28=0...................
If you mean: 9x squared+6x+1 = 0 then x = -1/3 and x = -1/3 therefore the quadratic equation has equal roots
It's equal to -X + 5 = Y (1, 4) (5, 0)
4x2 - 4x + 1 = 0 => (2x - 1)(2x - 1) = 0 => (2x - 1)2 = 0 There is one solution: x = 1/2. It is a repeated root of the equation.
