Not sure what the b factor is, but the answer probably is 1, the coefficient of x.
That expression can not be factored.
The GCF is x2.
This is an expression and you do not solve an expression, but you can factor this one.X2 + 3X4X2(1 + 3X2)========
-19
x2+2x-15 = (x+5)(x-3) when factored
x2+10x-24 = (x-2)(x+12)
(x + 7)(x - 5)
x2 + 6x + 8 =(x + 2)(x +4)
It is (x+6)(x-4) when factored
The expression x2 + 1x - 12 can be factored out as (x - 3)(x + 4)
x2 + 4x + 6 can not be factored. If you want, you can reduce it to an expression with a single x term by comleting the square: x2 + 4x + 6 = x2 + 4x + 4 + 2 = (x + 2)2 + 2
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.
