Solve for x - x2-9x plus 14 equals 0?
x - x2 - 9x + 14 = 0 ; whence, x2 + 8x = 14 , x2 + 8x + 16 = 30 , and x + 4 = ±√30 . Therefore, x = ±√30 - 4 .
Solve x2 - x equals 20?
-18
Solve x squared - x equals 20?
x2 - x = 20 x2 - x - 20 = 0 (x - 5)(x + 4) = 0 x - 5 = 0 and x + 4 = 0 So, x = 5 ans x = -4
X2 - 9x - 6 equals 0?
x2 - 9x - 6 = 0 x2 - 9x + (9/2)2 = 6 + (9/2)2 (x - 9/2)2 = 6 + 81/4 x - 9/2 = ± √105 / 2 x = (9 ± √105) / 2
The cube of a number equals the square of the same number find the number?
x3=x2 x3-x2=0 Factor out x2 x2(x - 1) = 0 If x2=0 then x=0. If x - 1 = 0 then x = 1. Therefore the number is 0 or 1.
