Of the five quadratics listed below, four of them have two distinct roots. The fifth quadratic has a repeated root. Find the value of the repeated root. -x^2 + 18x + 81 3x^2 - 3x - 168 x^2 - 4x - 4 25x^2 - 30x + 9 x^2 - 14x + 24
Please fix the LaTeX.
-x^2 + 18x + 81 = -(x - 9)^2, so this is the quadratic with a repeated root.
Can you please help me find the value of the repeated root? Thanks!
From the factorization, the repeated root is 9.
