anything x 0 = 0
x^2+5-6=0 (x+6)(x-1)=0 x=1,-6
-5, -6
No because in this equation x = -6 -6--6 = 0
x2 - 2x - 5 = 0 x2 - 2x + 1 = 6 (x - 1)2 = 6 x - 1 = ± √6 x = 1 ± √6
(x-5)(x-6) so x=5,6
x2 + 11x + 30 = 0 (x + 5)(x + 6) = 0 so the roots are -5 and -6
4
x2 + x - 30 = (x + 6)(x - 5)
X2 - 5X - 6 = 0 What two factor of - 6 add up to - 5 ?? (X + 1)(X - 6) So, X = - 1 ===
X + (-6) = 0 x = 6 6 is the answer
5 x 0 = 0 5 x 1 = 5
