which of the following is a factor of x2 - 5x - 6
When factored it is: (x-9)(x+4)
x2-5x+4 = (x-1)(x-4) when factord
3x2 + 15x + 6 = 3*(x2 + 5x + 2). There are no further rational factors.
x2 + 5x - 6 can be rewritten as (x+1)(x-6). Setting each bracket = 0 gives x = -1 or x=6.
x2+5x-6 = (x+6)(x-1) when factored
which of the following is a factor of x2 - 5x - 6
x -9
x2 - 5x - 6 = x2 - 6x + x - 6 = x(x - 6) + 1(x - 6) = (x - 6)(x + 1)
x2+5x+6 = (x+2)(x+3)
x2-5x-66 x2-11x+6x-66 x(x-11)+6(x-11) (x+6)(x-11)
x2 - 5x - 66 is a quadratic expression that factors out to (x - 11)(x + 6)
x(x2+5x+6)
X2 - 5X - 6 = 0 What two factor of - 6 add up to - 5 ?? (X + 1)(X - 6) So, X = - 1 ===
x - 3
x2 + 5x - 120 can not be factored.
You don't factor an equation. You factor an expression.So we'll forget about the "equals 0" for a second, while we factor "x2 plus 5x plus 6".x2 + 5x + 6 = (x + 3) (x + 2).Now, if you want this expression to be equal to zero, that can only happen when 'x' is -2 or -3.
