Factorization of quadratic equation in junior high school

Factorization of quadratic equation in junior high school


+Word multiplication
X ^ 2 ten (P ten q) x ten PQ = 0
(x + P) (x + Q) = 0
X1 = one P, X2 = one Q



If the coefficient of quadratic term is not 1, it's better to use factorization,


I want to get a few, write a few (1) x & sup2; - 10x-24 = 0, 2 (x + 1) & sup2; = 3x + 3, 3 5x & sup2; - 2x = 0, 4 x & sup2; - 4 = 0, 5 x (x + 2) = 0, 6 x (x-1) = x, 7 x & sup2; - 1 = 0, 8 2x & sup2; - 3x = 0, 9 x & sup2; + 2 √ 3 x + 3 = 0, 10 (x + 1) (x-1) = 2 (x + 1), 11 x & sup2; = 3 x, 12 √ 2
