6x squared+42x=0?

6x^2 + 42x = 0
6x (x + 7) = 0
6x = 0 or x + 7 = 0

Therefore, x = 0 or -7

a million) 4x^2 - 8x + a million = -4x 4x^2 - 8x + 4x + a million = 0 (2 x-a million)^2 = 0 ........ans. x = a million/2 2) x^2 + 11x / 3 = -10 x^2 + (11x / 3) +10 = 0 a million/3(3 x^2+eleven x+30) = 0 ......ans. 3) (x^2 / 7) - 2 - 6x = -2 (x^2 / 7) - 2 - 6x + 2 = 0 a million/7(x-40 two) x = 0 .............ans. x = 40 two

6x (x + 7) = 0
x = 0 , x = - 7

6x^2 + 42x = 0
6x(x + 7) = 0
