x squared -2x-3 equals 0 is the same as (x + 1)(x - 3) = 0
If x squared -10 = 0 then x = the square root of 10
True because in both equations x = 0 or x = -4
(x-3)(x-5) = 0
(x-3)(x-9) = 0
your equation is this... 2x3 + 11x = 6x 2x3 + 5x = 0 x(2x2 + 5) = 0 x = 0 and (5/2)i and -(5/2)i
x squared -2x-3 equals 0 is the same as (x + 1)(x - 3) = 0
If x squared -10 = 0 then x = the square root of 10
4, -5
True because in both equations x = 0 or x = -4
(x-3)(x-5) = 0
(x-3)(x-9) = 0
(x+4)(x-5) = 0
(x, y) = (-3, -3) or (3, 3)
Solve this problem -x squared -40x- 80 =0
Yes it is and well done.
If you mean: x2+9x+20 then it is (x+4)(x+5) = 0 when factored
